CORSA REDEFINES PERFORMANCE EXHAUST 
Corsa's straight-through design coupled with RSC noise cancellation technology allows them to tune out the undesirable low frequencies that cause drone, while reducing back pressure for your Chevrolet Impala. A reduction in back pressure allows the engine for your Chevrolet Impala to produce more horsepower and torque.

Patented Reflective Sound Cancellation (RSC) Technology

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.
The RSC design features a pipe running straight through the muffler, incorporating a full 360-degree air gap and allowing sound pressure waves to escape. The waves are channeled and then returned to the gap 180-degrees out-of-phase, canceling specific sound frequencies. All that remains is the clean, crisp sound of performance.

NO DRONE/RESONANCE
Due to patented RSC noise cancellation technology, your interior is whisper quiet at highway speeds.
GREAT PERFORMANCE SOUND
We tune in good sounds to cancel out the bad sounds without the use of baffles or interior steel wool packing materials.
INCREASED HORSEPOWER & TORQUE
Due to straight-through design, the result is increased flow and less back pressure.
INCREASED FUEL ECONOMY
Less back pressure and more power means your engine performs more efficiently.
