UUC/Corsa Performance Exhaust Systems

Performance exhaust systems, available for most current BMW models, provide a pleasing “sporty” exhaust tone, improved appearance, lighter weight, and genuine power increases.

·         Increased power.

·         Sporty yet refined sound.

·         Lower weight for better performance.

·         Attractive tip appearance.

·         Lifetime warranty.

·         Will not rust, made of 100% stainless steel.

·         Made in USA.

Co-developed with Corsa Performance and based on their exclusive Reflective Sound-Cancellation™ (RSC™) technology, each system is 100% stainless steel and made in USA. These are undoubtedly the absolute best "refined and sophisticated sounding" performance exhaust systems available.

 CORSA is one of the largest automotive and high-end marine exhaust tuning companies in the USA with engineering and manufacturing facilities in Ohio.

 The result of CORSA's extensive research and development for the BMW models is the new drone-free series of RSC™ exhaust systems, delivering pleasant sound at idle and cruise, and a muscular roar at high rpm. CORSA tuned these systems specifically to counter drone. Sound pressure waves are reflected within the muffler case and unwanted noise frequencies are canceled through patented Reflective Sound Cancellation™ technology. The result is a tuned muffler that produces the best sound and performance possible.

No Other Exhaust Manufacturer Delivers All Three:

 

No Resonance/Drone... due to our patented Reflective Sound Cancellation™ (RSC™) technology; your exhaust is whisper quiet at highway speeds. Increased Horsepower and Torque... resulting from a straight-through design, increased flow and less backpressure. 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, inverted within tuned chambers, and reflected back into the primary exhaust stream. Overlaying this inverted sound wave over the original effectively cancels out that tone. The system is designed in this way to cancel out the unwanted “drone” sound waves at cruising speed / engine load. 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 is tuned to eliminate passenger cabin resonance and produce just the "right" sound.

Frequently Asked Questions

A: Yes, emission control systems are completely unaffected. None of the UUC/Corsa systems affects any catalytic converter or other federally mandated emissions-control components.

A: No, the BMW computer (DME) is completely adaptive and will make all adjustments as required within a short period.

A: No. All systems are either a direct bolt-on design or slip-fit with clamps and are completely reversible.

A: Fully illustrated instruction guides are provided with every exhaust system, and any additional parts or hardware are provided.

A: All UUC/Corsa exhaust systems are designed to be very quiet and “mellow” at cruising rpm/speed and will not be intrusive on normal in-car conversation. At full throttle, the sound is dramatically more aggressive but is generally compliant with the sound restrictions in most municipalities, and some are certified compliant with the SAE J1169 noise level standard. Local municipal and state laws may vary.

A: All Corsa systems are covered by a limited liability lifetime warranty to the original purchaser.
