Product Description

The choice of an aftermarket exhaust is complicated. There are lots of choices. CORSA Performance Exhausts focuses on delivering the best of what you want to enhance your driving experience.

CORSA's Patented RSC Technology is so precise that no 2 vehicles are the same. Each system is acoustically engineered to eliminate the specific frequencies that create drone. Using aerospace based technology, sound waves are targeted, reflected and eliminated without impeding air flow or sacrificing horsepower, yet still delivering the sound to fit your vehicle.

The Exclusive patented RSC Muffler design delivers a bold, unique sound under throttle that defines your performance car, truck or SUV on the open road. But inside, you experience the quiet ride, where you can use your cell phone or listen to the radio. The patented RSC Muffler design features a straight through design that incorporates a full 360-degree air gap that sends targeted sound waves to specifically engineered channels. The waves are then returned to the gap 180-degrees out-of-phase, cancelling the specific "drone" creating frequencies. All that remains is the bold rumble that it the true voice of performance.

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).
