Corsa Performance Twin-Silencer Exhaust (TSE) system for 2001-2005 325i & 330i (sedan and wagon) and 2001-2006 325Ci & 330Ci (**no convertibles). Features mandrel-bent T-304 stainless steel tubing, TIG-welded seams, true bolt-on installation (no cutting or welding), polished dual 3" round tips, as well as 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).

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 325 or 330's inline 6 cylinder BMW engine. This is a complete cat-back system, which bolts to the factory catalytic converter and replaces everything rear of the cat on your E46 325 or 330. Made 100% in the USA in Corsa's Ohio facility, this exhaust features a lifetime warranty from the manufacturer.
