Product Description

Fits Premium Package ONLY and Requires Roush Quad Tip Rear Valance Modification

Application - This Corsa Sport Catback Exhaust System with Polished Quad Tips is designed to fit 2015-2016 Fastback GT Mustangs.

Sport Performance Sound - Mustang owners love the power and performance their Premium Package equipped GT's possess, especially when dropping it into a lower gear to pass slow moving traffic, but they find the sound of the stock exhaust a little anemic. So give your GT the exhaust note it deserves by upgrading to a Corsa Performance Sport Catack Exhaust System. Acoustically engineered and tuned, this Corsa Sport Catback will give your V8 Coyote powered Mustang a robust, sport performance sound under acceleration and a distinct rumble at idle, all without any annoying drone while cruising. As an added bonus a Corsa Sport Catback will also improve your Mustang's exhaust flow for an increase of 5 RWHP and 4 RWTQ.

Race Car Growl - Corsa Performance Sport Catback Systems feature a very unique double helix X-Pipe that replaces the factory resonator mid-pipe. The double helix "X" crossover design not only helps improve exhaust flow for an increase in power, but it also adds a crisp raspy, race car growl to the sound of your Mustang's exhaust.

RSC Technology - Corsa Performance engineers all their mufflers using their very own patented Reflective Sound Cancellation® Technology (RSC). RSC Technology is designed to give your Mustang's exhaust an aggressive sound under acceleration and a drone-free experience while cruising.

Quality Construction - Corsa Performance proudly manufactures their Catback Exhaust systems right here in the good ole USA. This Corsa Catback is mandrel-bent from 3" diameter, premium grade, 304 stainless steel tubing for excellent exhaust flow and enduring corrosion resistance. The system includes a double helix X-pipe and two high flow, straight-through sport mufflers. The mufflers feature a pair of mirror polished twin 4" Pro-Series tips. Step down flanges are included, so that this 3" Corsa Axle-Back can be installed with the factory 2.5" exhaust.

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).
