All Corsa systems are built to order and require a 10-14 business day lead time. Corsa Cat-Back Exhaust for 2007+ 335i models Reflective Sound Cancellation technology for the 335i
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. 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. How does it work?
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. . The Corsa Performance muffler design does not use conventional packing materials, and provides a totally un-restrictive exhaust flow for maximum power output.
The RSC335 is fully emissions-legal in all 50 states. There is no effect whatsoever on emissions and there will not be any "Check Engine" warning lights. "Best in class" build quality, made right here in the USA!
Construction enhancements include 100% mandrel-bent pipes, 4" PRO-series tips, and TIG-welded seams.
SOUND LEVEL CERTIFICATION
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. The test involves positioning a type 1, SIA compliant ANSI S1.4 - 1983 noise level meter, specifically as illustrated in the diagram to the left. Positioning is relevant, the tests are extremely specific in their scope and must be conducted under controlled conditions. RSC335 has been certified to meet the SAE J1169 sound test for 95dB noise limits and is therefore legal in the many states that use this test as their reference.
