Xtreme Aggressive Sound. Be heard long before being scene by installing a Corsa Performance Xtreme Cat-Back Exhaust System on your GT Mustang. Acoustically engineered and tuned, this Corsa Xtreme Cat-Back will give your 5.0L V8 Mustang a throaty, aggressive sound under acceleration and a deep growl at idle, all without any annoying drone while cruising. An Xtreme Cat-Back Exhaust is ideal for those GT Mustang owners who don't care if they wake up their neighbors. As an added bonus a Corsa Xtreme Cat-Back will also improve your Mustang's exhaust flow by 43% for an increase of 5 RWHP and 4 RWTQ.
Race Car Growl. Corsa Performance Xtreme Cat-Back 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 Cat-Back Exhaust systems right here in the good ole USA. This Corsa Cat-Back is mandrel-bent from 3 inch 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 Xtreme mufflers. The mufflers feature a pair of black chromed twin 4 inch Pro-Series tips. Step down flanges are included, so that this 3 inch Corsa Cat-Back can be installed with the factory 2.5 inch exhaust.
Application. This Corsa Xtreme Cat-Back Exhaust System with Black Chromed Quad Tips is designed to fit 2015-2017 Fastback GT Mustangs equipped with the factory Premium Chassis Package (Trim Levels: 400A/401A) and the 2018-2019 Fastback GT Mustangs that is Not equipped with the Active Valve Exhaust System.
Application Note. The 2015-2017 Model Years will require the use of the Roush Rear Valance 421894 or 421919 for proper installation (valance sold separately). Does not fit convertible models.
