 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!

These Supersprint section 1 straight pipes are designed to follow the larger pipe sizing of the Supersprint stepped headers. With straight pipes and headers, there will be no cats in the system, making this perfect for race or track-only cars. The straight design will be louder and let more of the S54 rasp to come through. With headers and the Supersprint race mufflers the sound is simply intoxicating. You can use this section with any other section 2 pipe and muffler.
