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!
NOTE: Supersprint engineers and manufactures complete exhaust systems. This part was designed to be used with the rest of the Supersprint system on this car but may be used on its own. Contact us for more details.

This Supersprint section 2 replaces the center resonator in the 128i 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. And with less restriction there is a slight horsepower and torque gain as well! This pipe fits best with the Supersprint rear muffler but may fit with other mufflers with professional installation.

This Supersprint center resonator is tuned to work with their muffler system to provide an aggressive but not wildly loud exhaust note. Supersprint makes two center section options - with or without a resonator. When planning your exhaust layout this will likely be the final section to choose. If you're deleting the secondary cats for more power you may want to opt for the tuned resonator to keep the exhaust note quieter. If you won't be deleting your secondary cats, opening up the resonator with straight pipes will allow more sound to come through. Or run with no cats and no resonator for the biggest - and loudest - power gains.

Supersprint designed this resonator section to replace the stock resonator when used with their performance rear mufflers. This resonator is a free-flow design that is also tuned to produce a low exhaust rumble sound and give the twin-turbo V8 more presence.

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.

This front section is a direct replacement for the stock 235i/335/435/M2 exhaust with one key difference - the Supersprint uses full 80mm piping for improved flow out of the turbo. One of the best and easiest ways of getting more power from a stock turbo is by helping it push exhaust gas and larger and smoother exhaust piping will help with that. Where the stock system is bent and crimped, the Supersprint is a full 80mm along its entire length. This section 1 will fit to the stock or Supersprint turbo downpipe and a stock or Supersprint section 2 exhaust.

Supersprint sport cats for the M5/M6 are designed to work with their performance headers and replace the stock secondary cats. The Supersprint sport cats are much freer-flowing than a factory-style cat. With less restriction, less effort is required to move the exhaust gasses which will free up horsepower and torque. This cat section will mount to the Supersprint merge collectors and then to a Supersprint or stock section 2. These are built with O2 sensor bungs pre-installed after the cat if you wanted to extend your stock post-cat O2 sensors (however, special software may still be needed).

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.

This Supersprint center section will delete the secondary silencer/resonator in the stock exhaust and fit with the Supersprint sport rear muffler. The front of this section is clamped to the stock secondary cats via a set of connecting pipes. By eliminating the resonator, and matched to the rear muffler, more engine sound can be heard. And with less restriction more torque and horsepower can be released.

The sporty sound is achieved from the accurate selection of the piping sections, of the unique inner silencer design, and dedicated to the specific vehicle model.
The same high care is kept in the choice of the outlet style, to ensure a pleasant car design customization
The installation procedure is easy and quick, because it exploits the same hangers of the stock exhaust.
No modifications, neither to the chassis, nor to the mechanical parts, are needed.
Every Supersprint exhaust system has been researched, designed and tested to insure additional power and to enhance overall performance. All design is validated by extensive testing which includes hours of dyno testing on Supersprint's Maha 4-wheel chassis dynamometer. In fact no other exhaust manufacturer, race team engine testing department or car manufacturer has the performance evaluating experience of Supersprint.
