Corsa Performance T-304 stainless exhaust system for 2001-2006 E46 M3.
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. The
Corsa system also eliminates the "Rasp" characterists of the stock
exhaust sound. This Rasp-elimination is accomplished just like the
earlier "Rasp-X" product. 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).
As well as the tuned sound and drone eliminating sound, the mufflers use
a straight-thru flow design for maximum flow and the least amount of
restriction. Decreasing the restrictive back-pressure results in more
horse power and torque, as well as the inspired sound this system
creates for your E46 M3's 3.2 lliter engine. This exhaust mounts to the
back of Section 1, replacing Section 2 and the rear muffler. It does not
replace the Section 1 or the exhaust manifolds (E46 M3 exhaust
manifolds contain the catalytic converters -- this exhaust does not
affect emissions at all). Made 100% in the USA in Corsa's Ohio facility,
this exhaust features a lifetime warranty from the manufacturer. Fits
all 2001, 2002, 2003, 2004, 2005 and 2006 M3 coupe and convertible.
