If you have already upgraded to the Turner midpipes this is your chance to step up to the full valved catback. See the details when creating your new Full Catback! With this Valved muffler and all installation hardware you can add to your Turner midpipes to make a full exhaust. When it comes to shopping for exhausts you want to find one that suits your driving style and sound preference. While one part of you wants to have a loud and aggressive sounding exhaust, there is another part of you that knows you don't want to wake up the neighborhood or annoy your significant other. Finally the answer to your dilemma, thanks to Turner motorsports you no longer need to choose between rowdy and tame. With the new your new light-weight performance exhaust you have the option to go from tame and tasteful to loud and rowdy. The Turner Valved exhaust was designed specifically for your E46 and there are no other options on the market like this. Control the tone and volume of your exhaust with the click of a button. With the valves closed you have a nice low tone and hearty exhaust note. When the valves are open you get complete unrestricted access to sound and power for when you're at the track or just in the mood to let it rip. The full catback exhaust from Turner features dual 2" stainless steel mid-pipes that connect directly to your factory downpipes. Within the mid-pipes is an integrated x pipe for a smooth flowing center section with lower amounts of back pressure which leads to increased performance and a smoother exhaust tone. The 2" mid-pipes crossover and flow into a 3" exhaust section and full 3" valved muffler. The muffler features integrated 3" exhaust tips for an aggressive look that fills out your rear diffuser to get the perfect appearance. Valved exhausts of this caliber can be found on new performance models, super cars and overall cars way above the price ranges of a nice E46. Surprisingly enough some E46's did come with a type of vacuum actuated mufflers which opened and closed the exhaust under certain rpm ranges, unfortunately by now the factory valve is damaged or the muffler no longer actuates. Although the factory valved muffler on E46's were great in theory, there was very little change in tone and was limited by your driving style. Taking notes from the original engineering process from BMW, the engineers at Turner revitalized this cool technology and made it better. The final product is a light-weight performance exhaust that features superior valving a great aesthetics! Part Design: Turner In-house designed and engineered using FARO ARM laser scanning technology and SolidWorks 3D CAD modeling for precision fitment. T304 Stainless Material in a natural finish - 1.25mm wall thickness, back purged and TIG-welded throughout 2"-3.0" Stainless Steel Mandrel Bent Tubing T304 Stainless Steel 12mm barbed exhaust hangers Tig-Welded in OE locations for precise fitment.​ 23 lb weight reduction from factory catback Designed for smoother flow path and less backpressure Kit Contents: 3.0" Valved muffler with integrated tips Valve controller with installation kit and 2 key fob controllers

Drop 10 lbs and replace your midpipes/resonator for a free flowing X-Pipe to get a smoother sound and decreased back pressure!

An X-Pipe can do wonders for your engine for performance and sound. Exhaust gasses come out of your motor in pulses from each individual cylinder, with a cross-over or x-pipe the exhaust gasses meet in the middle and combine. The result of the combining gasses is a smoother path leading to lower amounts of back pressure, a more free-flowing exhaust and leads to increase power and response. Combine with a new rear muffler for best results!

BMW's straight six motors have been referred to as sounding like chain-saws, and being "raspy" or "metallic". Transform your exhaust with our mid section exhaust with an integrated x-pipe to smooth out your exhaust tone and enjoy the sound of your M54! The mid section x-pipe comes with new hardware for connection to the downpipes and includes superior exhaust sleeves to slide over your factory rear section.

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 an ingenious 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 volume exhaust. With the valves open this exhaust is an absolute mental, untamable racecar. 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.

Upgrade your BMW E46 exhaust system with the Turner Motorsport X-Pipe, ditch the bulky factory midpipes and resonator, reduce backpressure, and let your engine breathe the way it should. This free-flowing X-pipe delivers smoother exhaust tone, improved throttle response, and a noticeable performance advantage over restrictive OEM components. Factory exhaust pulses exit each cylinder separately, creating turbulence, rasp, and unwanted backpressure. A performance X-pipe merges and balances these pulses, producing a cleaner, deeper exhaust note while increasing overall exhaust efficiency. For the best sound and power gains, pair the Turner X-Pipe with a high-flow performance rear muffler. BMW’s straight-six engines, especially in the E46 323i and 328i, are known for their metallic “rasp” under load. Turner’s mid-section with an integrated X-pipe dramatically smooths the exhaust character, enhancing tone without sacrificing flow. Each system includes upgraded hardware for the downpipe connections and premium stainless steel exhaust sleeves for a perfect, leak-free fit to your factory rear section. Features and Design: Turner in-house engineered using FARO ARM laser scanning and SolidWorks 3D CAD for exact BMW E46 fitment T304 stainless steel construction with natural finish, 1.25mm wall thickness, TIG-welded and back-purged for longevity 2.0" OD stainless steel mandrel-bent tubing for maximum exhaust flow T304 stainless 12mm barbed exhaust hangers, TIG-welded in OE locations for perfect alignment Direct-fit flanges designed to bolt to factory BMW E46 downpipes Over 10 lbs of weight reduction compared to OEM midpipes Engineered for smoother flow, lower backpressure, and enhanced performance on E46 323/328 models Kit Contents: E46 323i / 328i Mid-Section with Integrated Turner X-Pipe New rear exhaust brace New downpipe hardware (replaces seized factory studs) Dual stainless exhaust sleeve clamps for easy installation to the factory rear section
