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
This is what sets us apart from other exhaust manufacturers: RSCâ„¢ 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*
