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!

This set of left & right rear mufflers mount to the stock exhaust or to Supersprint Crossover pipes. Supersprint exhausts are made of 100% stainless steel for extended longevity. These mufflers produce a throatier growl from the engine without any dramatic aftereffects. What you get is a strong burble at idle and low rpm and a sporty rip at higher rpm. These mufflers use 4 round polished tips for a very distinctive and sporty appearance - the rear bumper valence will need to be trimmed around the tips.
