CORSA Exhaust, The CORSA Distinction No Other Exhaust Manufacturer Delivers All Four:

[1] No Resonance/Drone... due to our patented Reflective Sound Cancellation™ (RSC™) technology; your exhaust is whisper quiet at highway speeds.

[2] Increased Horsepower and Torque... resulting from a straight-through design; increased flow and less backpressure.

[3] Great Performance Sound... we tune in the good sounds and cancel the bad, without the use of baffles or steel wool packing material.

[4] Better Fuel Economy... less backpressure means the engine does not work as hard (especially if you can keep your foot out of it...).
