2001-2006 BMW M3 E46 2.5″ Cat-Back, Dual Rear Exit with Twin 3.0″ Polished Pro-Series Tips by Corsa (14567) Corsa Exhaust

CORSA Performance entered the exhaust category in 1998, re-writing the rulebook for what a performance exhaust should be with the launch of our revolutionary RSC® (Reflective Sound Cancellation®) Technology. RSC® Technology allows CORSA Performance the unique ability to selectively target and eliminate resonant frequencies that cause drone, by reflecting sound waves out of phase, while custom tuning the exhaust note. Since the debut of RSC® Technology in 1998 on the C5 Corvette, CORSA Performance has invested countless resources developing proprietary tools used in Perfecting the Science of Sound, resulting in world-wide recognition for high-performance, aggressive exhausts systems that eliminate drone.

Today CORSA Performance employs multiple forms of proprietary RSC Technologies and acoustic solutions to cancel resonant frequencies that cause drone and produce the desired exhaust tone. Every CORSA Performance exhaust system manufactured takes into account OEM design, desired performance output as well as interactions of the entire Exhaust System. During the development phase an RSC Technology is chosen that best attains the desired balance of acoustics resulting in hundreds of unique designs that cover our numerous vehicle applications. Rarely are any two Exhaust Systems featuring RSC Technology the same.
