Borla Cat-Back Exhausts
Corsa Performance T-304 stainless exhaust system for 2000, 2001, 2002 and 2003 E39 M5 V8. Features mandrel-bent tubing, polished quad 3" tips, and drone-free quiet-cruising, thanks to Corsa's patented Reflective Sound-Cancellation (RSC) technology. This technology is 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 180 degrees out of phase 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 result is quieter cruising with an awe-inspiring roar at full throttle. This system is amazingly quiet during normal cruising, due to the "no drone" RSC technology, yet still has an aggressive presence and full sound while under throttle. This makes for ideal sound for those that want an aggressive "roar" while driving hard, yet still want a more discrete lower volume for normal cruising. (Please check out the video below for a sound sample).
O2 Sensor Bung and plug. This weld-in bung allows an O2 sensor to be screwed into your exhaust system. It's required for custom exhaust systems, and is also useful for air/fuel ratio measurements when dyno testing. A threaded plug is included to cap off when not in use. Bung and cap/plug are both 100% stainless steel. The bung and plug are also available separately (in case you don't need both). Simply choose your option below.
