RSCE46M3 exhaust for 2000-2007 E46 M3 Reflective Sound Cancellation technology for the M3
Manufactured and engineered in the USA - unique technology called Reflective Sound Cancellation™. The result is a drone-free exhaust system, delivering a pleasant sound at idle and cruise and a muscular roar at high rpm. This exhaust for the M3 is an under-car system, replacing "Section 2" and the rear muffler. Rasp elimination is accomplished like our earlier 'Rasp-X' product. It does not replace the exhaust manifolds (M3 exhaust manifolds contain the catalytic converters - this exhaust does not affect emissions at all). This system is 100% compatible with the European headers and under-car catalytic converters.
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 technology, the stainless steel mufflers are tuned to eliminate passenger cabin resonance and produce just the "right" sound. [CLICK HERE FOR MORE DETAILS] The RSC muffler design does not use conventional packing materials, and provides a totally un-restrictive exhaust flow for maximum power output.
The RSCE46M3 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, 3" PRO-series tips, and TIG-welded seams.
