UUC Exhaust Systems

The all-new RSC36 is the absolute best performance exhaust system for '92-'99 M3, 328, 325 models (not for Compact/Ti). It is a full dual cat-back design, however the RSC36 is unique in that 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 the UUC and CORSA partnership is a drone-free exhaust system, delivering a pleasant sound at idle and cruise and a muscular roar at high rpm. Test vehicles for this development program included the M3 automatic, whose transmission programming "lugs" the engine at low rpm, resulting in a high potential for drone. CORSA tuned the RSC36 specifically to counter that situation and the results are impressive.

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 RSC36 is fully emissions-legal in all 50 states. Construction enhancements include 100% mandrel-bent pipes, TIG-welded seams, and true bolt-on installation (no cutting or welding required). Many statutory bodies around the world currently mandate that vehicles comply with stationary exhaust noise tests specifications - Generally based upon the "SAE J1169 Measurement of Light Vehicle Exhaust Sound Level under Stationary Conditions". California and various other states now have legislation that makes exceeding this limit an offense, resulting in a "fix it" ticket and required testing certification. RSC36 has been certified to meet the SAE J1169 sound test for 95dB noise limits. The test involves positioning a type 1, SIA compliant ANSI S1.4 - 1983 noise level meter. Positioning is relevant, the tests are extremely specific in their scope and must be conducted under controlled conditions.
