CORSA straight-through design coupled with RSC™ noise cancellation technology allows us to tune out the undesirable low frequencies that cause droning, while reducing back pressure. A reduction in back pressure allows the engine to produce more horsepower and torque. CORSA uses its patented Reflective Sound Cancellation™ (RSC™) technology to eliminate low frequency resonance while minimizing backpressure. Sound waves are reflected within the muffler case, producing a cancellation wave effect, with no flow restriction and without electronic devices.Corsa Exhausts Feature: - No Resonance / Drone - due to noise cancellation technology – RSC is whisper quiet at highway speeds
- Great Performance Sound - we tune in the good sounds and cancel the bad without the use of baffles or wool packing material
- Increased Horsepower & Torque - due to straight-through design = increased flow and less backpressure
