The all-new RSC36 is the absolute best "refined and sophisticated sounding" performance exhaust system for '92-'99 M3, 328, and 325.  CORSA Performance was engaged to design and manufacture the exhaust. Thanks to this unique partnership, the RSC36 is available exclusively through UUC.

CORSA is one of the largest automotive and high-end marine exhaust tuning companies in the USA with engineering and manufacturing facilities in Ohio and a patented, proprietary technology called Reflective Sound Cancellation™. CORSA consults to General Motors, Ford and Daimler-Chrysler and carries the title of "official licensed product" on its GM aftermarket exhaust systems.

The result of CORSA's extensive research and development on the BMW 3 Series is the new dronefree RSC™ exhaust system, delivering a pleasant sound at idle and cruise, and a muscular roar at high rpm. CORSA tuned this system specifically to counter drone. Sound pressure waves are reflected within the muffler case and unwanted noise frequencies are cancelled through patented* Refective Sound Cancellation™ technology. The result is a tuned muffler that produces the best sound and performance possible.

The CORSA Distinction
No Other Exhaust Manufacturer
Delivers All Three:

1] No Resonance/Drone... due to our patented Reflective Sound Cancellation™ (RSC™) technology; your exhaust is whisper quiet at highway speeds.

2] Increased Horsepower and Torque... resulting from a straight-through design; increased flow and less backpressure.

3] Great Performance Sound... we tune in the good sounds and cancel the bad, without the use of baffles or steel wool packing material.

How does it work?

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.

UUC RSC36 tips are
staggered to follow valance line
 resulting a pleasing appearance. 

This shows a muffler system designed
specifically for this application.
Typical aftermarket exhaust has
tips that are even, and do not line
up with valance.

in the application.
