Product Description

Install a CORSA Performance exhaust on your vehicle, and get the sound you want and the power you need. Hit the throttle and feel the power as it blends with the gutsy exhaust note. Let up and notice how quiet this exhaust is when cruising or idling. From the 100% stainless steel tips to the patented Reflective Sound Cancellation technology eliminating annoying cabin resonance, a CORSA exhaust gives you better improved performance, first-rate quality and engineering, in concert with power.

The exclusive, patented Power-Pulse RSC muffler design delivers the throaty exhaust tones that define your performance on the open road. But inside, you will experience the quiet ride, that until now, you've only dreamed about.

CORSA has now made it possible with RSC - Reflective Sound Cancellation technology - using aeronautical and space age noise-suppression technology. Sound waves are reflected within the muffler case, producing a cancellation wave effect - with no flow restriction and without electronic devices!

Quiet and efficient.

This system rocks. I got the touring system because I use this car as an everyday driver. Nice and quiet. I also had some electronic cutouts installed. So, quiet sleeper to obnoxious muscle car in 6 seconds. Highly recommended.
Very pleasing to the ears!

This is probably the best exhaust you can get for your Goat. Yes, there are other loud/louder ones, but when you combine the volume with the sexy tone this one offers, you can't beat that. There is absolutely zero drone. I highly recommend this mod!!

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).
