Corsa 08-12 BMW M3 E90 Black Sport Cat-Back Exhaust

The choice of an aftermarket cat-back exhaust is complicated. There are lots of choices. CORSA Performance Cat-Back Exhausts focuses on delivering the best of what you want to enhance your driving experience. *Aggressive Performance Sound* Our systems are all acoustically styled and engineered to match the make, model, and harmonics specific to your vehicle. Each system is designed to match the personality of a car and its owner *No Drone* This is what sets us apart from other exhaust manufacturers: RSC™ technology eliminates "problem" frequencies that cause interior drone/resonance at cruising speeds. You can add CORSA and enjoy your car at idle, on acceleration and while cruising down the road *Improved Horsepower And Torque* Patented non-restrictive Straight-through design reduces back pressure and frees up additional power. *Potential For Better Fuel Economy* Less back pressure and more power means your engine functions more efficiently and that translates into better fuel economy *Premium 304L Stainless Steel Construction* The combination of 304L stainless steel construction and the fact that our systems don't use cheap easily degraded packing materials ensure your product will last. *Limited Lifetime Warranty* The combination of 304L stainless steel construction and the fact that our systems don't use cheap easily degraded packing materials ensure your product will last *Included All Necessary Hardware And Full Color Instructions* Our systems come with top quality TORCA Clamps, that are also 304SS, and instructions that feature actual full color photos to make your install as simple as possible *50 State Emissions Legal* Since our systems are all designed to install rearward of the factory catalytic converter there are no emissions hassles. Just bolt it on and go. *Handcrafted In The USA* Every system is proudly manufactured in Berea, OH, USA.
