Rasp Terminator for the E46 M3 (also for MZ3 and Z4M) is a tuned front section that: Greatly reduce rasp from the S54 engine Balance exhaust pressure for each bank with H-pipe crossover The S54 rasp is excessive and tuning it out requires the right combination of resonators, placement, and tubing size. CPI designed their own section 1 after other designs on the market fell short. Rasp is reduced by approximately 80% on a M3 equipped with aftermarket headers. The latest RTX incorporates an H-pipe crossover that equalizes exhaust pressures in both banks before they merge for section 2. This reduces turbulence and improves exhaust flow. While not designed to gain power and torque, dyno testing showed slight gains with this system. Fitment has also been improved for better ground clearance. Tubing is a full 2.36" (60mm) and 304 stainless steel throughout. It will bolt on to most headers and to any section 2 that uses the factory-style flanges.

Connecting Pipe Kit For OEM Center Muffler. This is only needed when fitting the Supersprint mufflers to the stock resonator. When installing the Supersprint X-pipe (res.-delete) and the Supersprint mufflers, the connector kit is not needed. 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 preference. 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!

 The Supersprint 'Race' rear muffler system is one step beyond the standard Sport mufflers. Don't be fooled by the name - the 'Race' mufflers are designed for street use and the name only distinguishes it from the quieter standard Sport system. With the stock system the sound is very subdued. With the 'Race' mufflers the sound is much more noticeable and more aggressive - a perfect sound to compliment the assertive nature of an M Coupe or Roadster. You will hear this exhaust but it will not be intrusive or sound out of place on a civilized sports/GT car like the MZ4. The Supersprint center pipes to delete the rear resonators for more volume can be a welcome addition. 

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!

Achieving precise exhaust fitment can be tricky—especially when the exhaust hanger has room to slide. This movement can cause annoying rattles or even lead to contact with the underbody or rear bumper. The ECS Tuning Exhaust Locking Collar offers a simple and effective fix. Designed to clamp securely around the exhaust hanger, this collar keeps everything firmly in place, eliminating unwanted movement.

Crafted from high-strength 6031 billet aluminum and finished in a sleek black anodized coating, it delivers both durability and corrosion resistance. With this collar in place, your exhaust stays exactly where it should—no rattles, no surprises.

Product Design:

Made from precision machined 6061 aluminum Black anodized finish Stainless steel M5 X 0.8mm hardware Installation & Support:

Install the locking collar around your exhaust hanger, position the hanger in place, and snug the locking collar down in place against the hanger! ECS Exhaust Hanger Locking Collars are available for 10mm and 12mm exhaust hangers. Please measure your hangers before ordering. The 10mm locking collar can be found HERE.
