Product Description


This Corsa Performance SPORT exhaust system keeps the factory over-the-axle pipes in place (which is where the exhaust valves are) so you can retain the factory valve control, so they call it a "Valve-back" system. This is a dual muffler, dual rear exit system with special tips. Corsa claims a flow increase of 16.9% over stock mufflers and a horsepower increase of about 3 horsepower. This system will save you about 2 pounds over the stock mufflers.

Corsa's patented RSC technology is designed for an aggressive sound under acceleration combined with a drone free experience during cruising, a claim that nobody else can make. Every system and muffler is engineered and designed specifically for the vehicle it's going to be installed on and is not generic in nature.

CORSA's Reflective Sound Cancellation RSC Technology allows acoustic designers to create a tone, styled specifically to fit the personality of your vehicle, without any drone while cruising. CORSA takes it a step further to develop three types of sound to fit your personal tastes and needs as well. Each system offers the distinctive CORSA sound on the throttle and a whisper-quiet cabin while cruising and also deliver increased flow and horsepower you demand. The differences are simply YOUR choice.

Xtreme - Aggressive and Deep, Xtreme sound levels are found on most of our American Muscle offerings including Corvette, Mustang, Challengers and Camaros. Race inspired, it offers the biggest sound with the deep throaty growl.

  • Most aggressive sound level offered
  • Wake the neighbors on demand
  • Deep growl at idle
  • Bold during acceleration
  • Screams at high RPMs
  • Not recommended for highly modified vehicles

Sport - Robust and Bold, Sport sound levels offer our popular CORSA growl when on the throttle. Perfect for those who want to be noticed on acceleration or when passing, but delivers the perfect cabin experience. Ideal with other moderate performance modifications such as air intakes.

  • High performance sound
  • Annoy the neighbors on demand
  • Distinct rumble at idle
  • Aggressive sound through the gears
  • Corsa's most popular sound level

Touring - Reserved but Distinctive, Touring systems offer sound that are just a notch above stock. Perfect for those who are adding other major HP modifications to their car such as headers, to keep the sound blended perfectly at cruise.

  • Slightly louder than stock
  • Let the neighbors know you're there
  • Quiet at idle
  • Not available for all applications

All systems are designed to cancel specific sound frequencies, allowing for a NO DRONE interior at cruise. You are left to choose the sound on acceleration that best fits your style (and relationship with your neighbors).
