E46 M3 Performance Valved Cat-Back Exhaust:

The wait is finally over, if you have been driving your E46 M3 around with a stock exhaust or are looking for your final exhaust setup we have you covered! Welcome to the world of ingenious designed exhausts that can meet your every driving need. Our new E46 M3 catback Exhaust is a stunning example of both engineering and art with sounds to please your ears and a sight to remember. Our catback is a lightweight and free-flowing exhaust that features two independent valved mufflers and a brilliant mounting system that is a pleasure to install and easy to perfectly dial in the exhaust fitment. Weighing 19lbs or less than your factory exhaust, featuring mufflers specifically designed for the S54 this exhaust is able to provide two completely different driving experiences.

With the exhaust valves closed the refined driving experience will blow your mind; while daily driving with closed valves there is a perfect bump in volume over the factory exhaust which allows you to hear and feel your rpms with a smooth exhaust note that shows your true passion for your iconic vehicle.

Now on to the real action, what you have always wanted but never wanted to commit to. Some days you just want to put the pedal to the floor with unlimited amounts of exhaust volume with your high revving 6 cylinder. Here is your opportunity to unleash the pure sound of your S54 while having the choice to change back to a respectable volumed exhaust. With the valves open this exhaust is an absolute symphony. Starting off from a stop with the valves open there is a significant increase in volume over the valves closed. When entering in to the 2000 rpm range you begin to experience the slightest taste of how satisfying the exhaust is going to sound. As you approach 4,000 rpms and higher you now have started to open up the can of worms, you can feel the free-flowing path of the exhaust with limited to no resistance, far superior to the factory exhaust. Anything after 6500 rpms is an absolute statement of exhaust. Over 6500 rpm is a sonorous note that lives rent free in the enthusiasts mind that can make a believer out of anyone who doubted the capable E46 M3. Once you are done having your fun and have experienced your S54 more than you ever have all you do is make one button click on your valve controller and you are back to high class and refinement. Truly the best of both worlds and a school girl giggling experience anytime you want.

E46 M3 Euro Style Carbon Front Lip:

Our unique and carefully designed front lip for the E46 M3 focuses on enhancing the car's aesthetics while preserving its natural beauty. This front lip is constructed of high-gloss, 3mm thick, 2x2 carbon fiber that adds a tasteful accent to the bumper while being strong and lightweight!

This aesthetic piece was crafted to stand out from other options available on the market by incorporating design elements that draw inspiration from the stock bumper but reimagines them in a way that sets it apart. Rather than overcomplicating the car's body styling, the goal was to seamlessly integrate the front lip with the existing design. This approach aims to enhance the car's body styling rather than overshadow it.

This versatile design is suited for both track use and everyday driving on the streets. Our E46 M3 front lip was designed to strike a balance between uniqueness and performance oriented aesthetics, while complementing the car's existing design. This is a clear cut choice front lip for someone looking to enhance the look of their M3.

Once you see your M3 with this front lip from, you will no longer think the front end is complete without it. Rounding out the near perfect car, this front lip completes the front end by filling out the open space underneath and sets the stage to enjoy the timeless body styling incorporating a curvature that compliments the front bumper.

The Supersprint rear resonator for the E46 M3 is designed to help you tune your exhaust to your personal taste. If you're not a fan of the stock raspy exhaust note of the M3 this Supersprint resonator can help to reduce it. Or if extensive exhaust modifications have made the exhaust too loud this resonator can help quiet and dampen the overall volume. This fits in section 2 of the exhaust - after the front resonator section 1 and before the rear muffler.

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. A Supersprint exhaust rewards you with a terrific sound, long lasting construction and excellent fitment. The Supersprint sound is very 'European' which fits the sporting sophistication of BMWs perfectly. Most systems are also modular - sections can be added or removed to custom tailor the exhaust sound to your preferance. Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

Enhance your BMW's exhaust system with the all-new Magnaflow Universal Muffler, available at an exceptionally affordable price point. Say goodbye to noisy and inefficient mufflers with this high-performance solution.

The Race Series muffler is meticulously designed for uncompromising performance, delivering an aggressive racecar-inspired sound. Its genuine straight-through design ensures the utmost high RPM power, while the 2.5" or 3" perforated core effectively eliminates backpressure, optimizing exhaust flow.

This muffler stands as the ideal choice for dedicated racers, turbocharged engines, nitrous oxide fuel systems, or vehicles equipped with wild cam applications. It boasts a 2.25" inlet, a 24" overall length, and a 4" diameter round, angle-cut tip.

Kindly note that this muffler is of universal fit for rear exhaust and may necessitate welding or fabrication for installation, as it is not a direct bolt-on component for any specific vehicle.

The crowning touch to an exotic and wicked sounding E46 M3! The Supersprint Race mufflers are very popular for the shriek they add to the S54's exhaust note. A full Supersprint system with these mufflers is one of the sexiest E46 M3 exhaust sounds we've come across - especially in a tunnel! The Lightweight Race mufflers are the capstone to that system. You can use them with any other center section or with the Supersprint section 2 (with or without a resonator).

Part#: IKON-E46
Back Ordered

What makes the IKON unique?
Like all Rogue Engineering products, the IKON exhaust system is entirely designed and developed in the US in our facility in Hohokus, NJ.  By doing the development, fitting, evaluation, and testing here, you're assured a product that not only looks and sounds great but a product you can have installed with confidence.

The budget-minded enthusiast will quickly notice that the first IKON offering, for the BMW E46 325/330 is price much lower than our DMS exhaust.  With a price of only $550, this is undoubtedly the most affordable BMW specific exhaust offered to date.  Isn't it time an affordable exhaust solution be available for the E46?  

By utilizing a custom-made, single muffler (instead of producing two, individual mufflers in our DMS system), Rogue was able to save manufacturing costs with this simpler design, and pass this savings to the performance customer.  Many enthusiasts do not pay particular attention to the shape or size of the muffler, as long as it fits well and sounds good.  The RE IKON fits this bill perfectly.

How much performance should I expect to gain?
In testing, replacing only a muffler or even the complete exhaust system on an E46 yields small measurable gains.  Of course, these minute gains may be depicted on a carefully constructed dyno chart.  Rogue Engineering looks at an exhaust with reality in mind, designing the exhaust to deliver great looks and sound, with minimal issues of fit.  Of course, all of this at an affordable price would be a bonus.  These are features that the Rogue Engineering IKON deliver!

For real-world exhaust performance gains, this typically means replacing the largest restriction, the catalytic converters, located in the factory exhaust manifolds.  From there, free flow aftermarket catalytic converters could be added downstream, after the exhaust gas velocity had an opportunity to accelerate out of the engine, allowing for the most LEGAL gas velocity allowable.  This course of action, however, can typically can exceed more than $3000 plus installation.

Replacing the ENTIRE factory exhaust system (resonators and rear muffler) with larger tubing WITHOUT addressing the largest restriction is an exercise in futility.  This kind of exhaust "upgrade" will generally cost needless additional installation charges, fit issues (can 6 clamps on an exhaust REALLY fit like factory?), and ultimately, drain your wallet faster than a Bugatti Veyron. 

IKON Features
Just because the IKON exhaust system is easy on the wallet does not mean you are getting short-changed.  Features of the RE IKON E46 system include:

  • Only 21 pounds (replaces the 30-pound unit from the factory)
  • Full 304 Stainless Steel construction
  • Mandrel bent, dual 57mm tubing (stock is dual 50mm), allowing for increased air flow yielding positive performance gains.
  • Mill-finished pipes and muffler, mirror polished dual 3" angle cut, double-walled, staggered tips.
  • Entire exhaust utilizes TIG welded construction
  • Deep tone (stock center resonator is retained)
  • Maintains BMW factory warranty
  • Rogue Engineering logo tastefully stamped in the body of the muffler
  • Adjustable mounting positions allow variable positioning with aftermarket bodywork
  • Can be clamped or welded (because factory exhaust must be cut, professional installation recommended)

Free ground shipping! Fan of the rasp that comes from the S54 engine? This front exhaust section replaces the single resonator in the US exhaust (or the cats in Euro models) with a straight-through pipe. This can be a direct bolt-on to the stock or Euro headers and includes rear O2 sensor ports (for Euro models, must be plugged for US models). You can use this with the Supersprint resonator delete section 2 pipe for the max rasp effect. Or mount it with any other section 2 exhaust to fine-tune your sound. Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price, Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. A Supersprint exhaust rewards you with a terrific sound, long-lasting construction, and excellent fitment. The Supersprint sound is very 'European' which fits the sporting sophistication of BMWs perfectly.

Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation! This part alters or deletes the emissions equipment on your car. Because of this, we require a waiver of emissions compliance to be signed and sent in to Turner Motorsport.

BMW's original muffler hanger (part number 18201401797) works great at first but tends to fail over time, leading to sloppy exhaust movement and excessive noise. This failure is due to both heat and the heavy exhaust wearing down the hanger until it eventually tears, allowing the exhaust to shift around freely, banging off of nearby components. In order to address this common problem, Powerflex developed their own polyurethane rear muffler hanger that features a heavy-duty, yet lightweight, machined aluminum bracket. Polyurethane is significantly more resistant to the effects of heat and weight over time compared to rubber, meaning you can expect this exhaust hanger to last many times longer than your stock BMW hanger.

Section: center section with resonator, rear muffler (header/cat-back)
Installation: bolt-on to header, clamps elsewhere
Tip Style: dual round 76mm Borla angle cut
Power Gain: +5hp

Borla completely re-engineers the exhaust on the E46 325/330 with a tuned all-stainless cat-back system. The E46 Borla bolts straight to the factory manifold and uses all of the factory hangers for an easy and seamless install. Your factory exhaust can come off as one complete piece and bolt this in its place! This is a full stainless system - T304 inside and out for maximum corrosion resistance. The Borla flows better than the stock system too for increased performance, even over the stock ZHP system. But we love the sound of this system the most - deep and with plenty of rumble to set it apart from the stock sound. It's a tuned system, with front resonator and rear muffler, to be louder than stock but not excessive. It's also a lot lighter than the stock system at only 33lbs from nose to tailpipe.

Read what Borla owners have to say:
"The difference over stock is noticeable the instant you turn the key. It begins with a deep muted rumble at engine start. Between 1200-2000rpm, you are treated to a nice throaty (and somewhat loud) growl. Between 2500-3500rpm, the deep growl reveals a slightly deeper, more melodic mechanical rev-up. Once past 4500rpm, the car begins to sound surprisingly stock, all the way up to redline. Lifting off the gas reveals a slightly more pronounced "burble" that settles into a low rumble as revs drop back to idle. At steady cruising speeds, the exhaust does not drone. Planting your right foot brings back that wonderful low growl."
"...the Borla is a very well built unit. Very civilized exhaust note... more agressive, yet not obnoxiously loud."
"I can easily say the Borla exhaust is much better than the X&X exhaust. My brother has the Borla on his 330i ZHP, and I had the X&X on my 330i. The X&X exhaust didn't have the quality of engineering compared to the Borla. The X&X was louder, and had horrible resonation - unacceptable for street use. The Borla is bolt-on, excellent quality, and hangs perfectly straight. The sound is a bit louder than stock, yet never "rice" or obnoxious."

Every Borla is made with 304 stainless steel for the internals and muffler body. Unlike other systems that can use coated aluminum, mild steel, or 409 stainless, the Borla uses true 304 stainless on the inside as well as the outside. This prevents the muffler from rusting and deteriorating from the inside out. Borla guarantees every muffler with a 1,000,000 mile warranty. Turner Motorsport has been the leading Borla dealer for BMW exhausts since we sold our first system in 1996, including using Borla Exhausts on all of every Turner BMW racecar.

When building your vehicle for the track, there are a lot of considerations to take into account. One major factor is your exhaust system. Many exhaust systems are only designed for so much exhaust flow, which can really limit the total amount of potential power your engine can produce. To address this issue with heavily tuned, turbocharged, or supercharged E46 M3s, Supersprint now offers a new line of high performance Center Twin-Pipe Exhaust Pipes that are designed to provide you with a significantly higher exhaust flow than their original performance exhaust pipes, 787503 (Resonated) and 787513 (Non-Resonated), designed for street and light track performance.

This twin pipe system utilizes two high flow pipes instead of a single large pipe, allowing for up to 25% greater total exhaust flow. Thanks to the increased total flow, these center pipes are capable of supporting S54 engines producing over 400whp, perfect for all highly modified street cars or performance track vehicles.

This specific option offer's pipes that are resonated to prevent excessive noise and drone that may be experienced at cruising RPM speeds.

Supersprint revised their rear muffler designs to offer this 'Generation 2' version - smaller body and freer flow than the standard Supersprint muffler but quieter and more civilized than the full Lightweight Racing mufflers. It's still lighter than the stock original or standard Supersprint mufflers. The sound is a more refined version of the full racing mufflers with less drone and quieter overall but still with plenty of ripping S54 aural tone.

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. A Supersprint exhaust rewards you with a terrific sound, long lasting construction and excellent fitment. The Supersprint sound is very 'European' which fits the sporting sophistication of BMWs perfectly. Most systems are also modular - sections can be added or removed to custom tailor the exhaust sound to your preferance. Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

The Supersprint rear muffler is a subtle and pleasing sound upgrade on the E46 325 and 330. If you have felt that the stock muffler is too innocent and quiet this could be the perfect audio upgrade for you.

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. A Supersprint exhaust rewards you with a terrific sound, long lasting construction and excellent fitment. The Supersprint sound is very 'European' which fits the sporting sophistication of BMWs perfectly. Most systems are also modular - sections can be added or removed to custom tailor the exhaust sound to your preferance. Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

Want more rasp and volume to come through from your exhaust? This Supersprint section 2 will replace and delete the factory resonator that sits before the muffler. Without the resonator there to dampen the sound the overall volume will increase and let more S54 rasp come through. Combine this with the Supersprint section 1 straight pipes for even more Motorsport rasp. This section 2 pipe will bolt up to a stock section 1 or cat section and any muffler. It's perfect for getting just a little more volume from your stock exhaust without changing the muffler.

The Dinan sport muffler is designed to compliment the E46 M3 and not overpower the driver and passengers with harsh tones. Dinan engineers their exhausts to sound great and be a natural fit to the character of the car as well as produce more power and torque. Dual 3.5" stainless satin black tips engraved with the Dinan logo fill out the rear valence. Annoying highway drone has also been engineered out of the system. Dinan uses only 304 stainless steel in their systems for the maximum corrosion protection. This system replaces the factory rear mufflers at a pre-determined cut point on the stock exhaust, which makes for an easy installation and you can reinstall your original mufflers using factory hardware. Detailed installation instructions are included.

For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty. Dinan believes so fully in their “total package” approach that once your car has been fitted with enough of their parts, they celebrate your conversion from stock to Dinan with an exclusive trunk badge, displayed proudly by BMW enthusiasts everywhere. The Dinan sport muffler is worth 3 point towards your Dinan badge.

Please note: only the passenger-side tips are functional (exhaust exits from the two right side tips only). The driver's side tips are only for aesthetics. Dinan has engineered it this way to minimize drone.

This Supersprint section 2 replaces the second of two resonators in the 323/328 exhaust. By deleting resonators you can gain a little more volume from the exhaust. This is especially good if you're a fan of the stock exhaust sound and just want to hear more of it. Replacing one resonator makes a moderate difference but replacing both section 1 and 2 will be a dramatic increase in sound. And with less restriction there is a slight horsepower and torque gain as well!

Corsa's TwinSilencer Exhaust will change the sound of the E46 325/330 from a mild mannered commuter car to a true sports car. Corsa has designed a E46 performance exhaust with a tuned aggressive sound that is worlds apart from the stock ho-hum exhaust. But thanks to their innovative RSC technology this exhaust stays civilized at normal speeds and RPM. This is a sport exhaust that you can live with on a daily basis but it opens up when you get on it. This Corsa kit is known as the "Light" version and includes the rear muffler only, after the rear axle. It has the same mufflers as the full cat-back TSE3 exhaust but replaces only the rear muffer. This gives you nearly all of the sweet Corsa sound but a more accessible price point. Tips are available as polished or black and laser engraved with the Corsa logo. The black tips have an innovative coating that won't chip or flake and provides outstanding corrosion resistance.

Although known as the Twin Silencer Exhaust (TSE3) this system almost has dual personalities. When driven aggressively it produces a throaty and charismatic exhaust note. It has plenty of burbles and pops that a performance exhaust should have and compliments other performance upgrades you may have on your car. But when driven lightly there's only a slight hint of sporty sound. It becomes a subdued version of its other self and completely livable on daily and highway trips with NO DRONE! You can use it on a daily driver without it being annoying or intrusive and then let it off its leash for the weekend fun runs.

Reflective Sound-Cancellation (RSC) technology - This feature is a patented non-electrical noise control system, where engine sound (pressure) waves are reflected in passages inside the muffler 180 degrees out of phase to cancel out unwanted sound waves. The result is a tuned muffler that "cleans up" the noise without eliminating the pure sound of power associated with a high-performance vehicle. Using the Corsa technology, the stainless steel mufflers are tuned to eliminate passenger cabin resonance and produce just the "right" sound. The result is quieter cruising with an awe-inspiring roar at full throttle. This system is amazingly quiet during normal cruising, due to the "no drone" RSC technology, yet still has an aggressive presence and full sound while under throttle. This makes for ideal sound for those that want an aggressive "roar" while driving hard, yet still want a more discrete lower volume for normal cruising.

This is an axle-back system, which replaces only the rear mufflers of the stock 325/330 exhaust. It's very easy and straightforward to install and the rest of the exhaust can remain on the car (the original muffler is cut from the exhaust). Detailed photographic instructions are included. This system is 100% Made in the USA and carries a lifetime warranty from the manufacturer. This exhaust is emissions legal in all 50 states (no effect whatsoever on emissions, and no "Check Engine" warning lights).

This cat section will mount to the Supersprint headers (p/n 787401) and then to their section 2 (p/n 787403).

The catalytic converter is an emissions device that converts the exhaust gasses exiting the engine into a less toxic substance. This is achieved through the internal honeycomb monolith, washcoat, and the catalyst itself that commonly consists of a mix of precious metals. Unfortunately the catalytic converters do not last forever, and can be damaged if the engine is running too rich on fuel. If you're getting an oxygen sensor fault, and the sensor is ok, the likely cause is a failed catalytic converter. Relieve worry about an upcoming emissions test and replace your faulty or damaged catalytic converter.

Supersprint metallic sport catalytic converters are sourced from HJS of Germany. For 30 years HJS has been supplying motorsports teams with sport cats when rules required them. HJS is now a worldwide leader in sport cat technology and performance. Rally cars, German DTM, and Formula 3 all rely on HJS for clean, reliable horsepower. Supersprint works closely with HJS to spec a catalytic converter that is correct for the vehicle and engine package. This allows for a substantial increase in flow but which, at the same time, keeps the environmental specs within European limits. With any high-flow catalytic converter, special software or other work may be required to keep emissions fault codes and check engine lights from displaying. Supersprint catalytic converters are sold for track and other off-road uses only.

When building your vehicle for the track, there are a lot of considerations to take into account. One major factor is your exhaust system. Many exhaust systems are only designed for so much exhaust flow, which can really limit the total amount of potential power your engine can produce. To address this issue with heavily tuned, turbocharged, or supercharged E46 M3s, Supersprint now offers a new line of high performance Center Twin-Pipe Exhaust Pipes that are designed to provide you with a significantly higher exhaust flow than their original performance exhaust pipes, 787503 (Resonated) and 787513 (Non-Resonated), designed for street and light track performance.

This twin pipe system utilizes two high flow pipes instead of a single large pipe, allowing for up to 25% greater total exhaust flow. Thanks to the increased total flow, these center pipes are capable of supporting S54 engines producing over 400whp, perfect for all highly modified street cars or performance track vehicles.

This specific option offer's pipes that are non-resonated for a more aggressive sound that is perfect for the track and automotive enthusiast.

Fits the following Vehicles:
2001-2006 E46 BMW M3

This is the original Supersprint street rear muffler for the E46 M3. It's a direct replacement for the stock rear muffler but with less restriction and better flow. This exhaust is not overly loud (conforming to European noise restrictions) and no drone but is larger and heavier than the other Supersprint mufflers. It makes a deeper tone than with slightly more rasp than the stock system.

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. A Supersprint exhaust rewards you with a terrific sound, long lasting construction and excellent fitment. The Supersprint sound is very 'European' which fits the sporting sophistication of BMWs perfectly. Most systems are also modular - sections can be added or removed to custom tailor the exhaust sound to your preferance. Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!
