E90 M3 UUC/Corsa Exhaust
http://www.bimmerforums.com/forum/cl...el-tips-169907 Used 18 months (approx. 18k - 20k miles) on a sedan in good condition. This is a drone-free exhaust system, delivering a pleasant sound at idle and cruise and a muscular roar at high rpm. Reflective Sound-Cancellation (RSC) - a non-electrical noise control system without the complication of incorporating the use of electronics or speakers. Essentially, engine sound (pressure) waves are reflected in passages inside the muffler to cancel out unwanted sound waves. The result is a "tuned" muffler that "cleans up" the noise without eliminating the pure sound of power associated with a high-performance vehicle. Using this Corsa technology, the stainless steel Corsa Performance line of mufflers are tuned to eliminate passenger cabin resonance and produce just the "right" sound. . The Corsa Performance muffler design does not use conventional packing materials, and provides a totally un-restrictive exhaust flow for maximum power output.
