We just updated our site with the Corsa Performance T-304 stainless exhaust system for E90/E92/E93 M3 (sedan, coupe & convertible). Special Introductory Offer is listed on our site for the months of August & September (2012). Click Here for E92/E93 Coupe/Cabrio and Click here for E90 Sedan!!

Features mandrel-bent tubing, polished quad 3" tips (double-walled, angle cut and staggered), and drone-free quiet-cruising, thanks to Corsa's patented Reflective Sound-Cancellation (RSC) technology. This is a drone-free exhaust system, delivering a pleasant sound at idle and cruise and a muscular roar at high rpm.

Straight-through, nonrestrictive design specifically tuned for the M3.
Flow bench-tested 6.7% GAIN in exhaust flow vs. stock system.
16 LBS. LIGHTER than stock system.
Premium stainless steel construction, crafted with pride and precision in the USA.
Patented CORSA Reflective Sound Cancellation™ “NO DRONE” Technology.
Limited LIFETIME WARRANTY for as long as you own your M3.
Includes hardware and color installation guide.
50-state emissions legal.

NOTE: CORSA Performance exhaust systems are not warranted to meet any specific local, state or federal noise ordinances. Please check applicable laws before installing.

How is this accomplished? The RSC 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 gives your E90/E92 M3 an ideal sound for those that want an aggressive "roar" while driving hard, yet still want a more discrete lower volume for normal cruising.

As well as the tuned sound and drone eliminating sound, the mufflers on this E90/E92 M3 system 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 M3's 4.0 liter V8 engine. There is no effect whatsoever on emissions, as this system does not replace or inhibit the your

M3's factory catalytic converters, so there will not be any "Check Engine" warning lights. Emissions-legal in all 50 states. Made 100% in the USA in Corsa's Ohio facility, this exhaust features a lifetime warranty from the manufacturer. Includes full installation instructions, with detailed photos for easy and straight forward installation.

We just installed a set of the mufflers on a Sedan, along with an ESS Supercharger Click here for the complete installation images.
