The Supersprint rear mufflers for the turbo Z4 is a subtle sound and performance improvement for those that think the stock muffler is too tame. This sport rear muffler is a free-flowing design with larger piping to improve flow and tune the sound. With the stock cats in place the sound is still subdued but the Supersprint muffler makes an alteration to the exhaust note to be a little more sporty and aggressive but not intrusive or obnoxious. This system includes the center X-pipe with slightly oversized piping for improved flow over the stock system. This system uses two exhaust tips per side, giving more muscle and presence like BMW uses on their "M" models.

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!
