  Corsa

Corsa Exhaust System
Corsa Exhaust System, Hummer H2



CORSA Exhaust straight-through design coupled with RSC noise cancellation technology allows CORSA 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 System Features:
  • No Resonance / Drone - due to noise cancellation technology RSC is whisper quiet at highway speeds
  • Great Performance Sound - 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

CORSA RSC TOURING exhaust system responds with a more reserved, deep, V-8 sound, yet throaty under acceleration.

CORSA RSC SPORT exhaust system is best described as producing a bolder sound most evident between 3000 - 5000 RPM WOT.
