Description
Aggressive Exhaust Note. A Stainless Works 3" Retro Chambered Cat-Back Exhaust system will add the loud aggressive exhaust note of a classic 60's muscle car to your modern coyote powered S550 GT Fastback. This Cat-Back not only sounds great, but also improves exhaust flow with the included X-Pipe for an increase in horsepower, torque and performance.
Race Car Growl. The included X-Pipe not only helps increase power, but it also adds a loud raspy, race car growl to the sound of your exhaust with its modern "X" crossover pipe design.
Stainless Steel Construction. Constructed in the USA from mandrel bent 3" diameter 304 stainless steel tubing for strength and superior corrosion resistance, this Stainless Works Mustang Cat-Back Exhaust System features two round retro chambered 2.5" core mufflers that end with mirror polished 304 stainless steel slant cut resonator exhaust tips.
Lightweight. This Stainless Works Cat-Back Exhaust System is 22 lbs. lighter than the factory Ford catback system, making it perfect for track and drag racers looking to shed unwanted weight in the pursuit of quicker times.
Direct Fit Upgrade. This Stainless Works Mustang Cat-Back with X-Pipe includes all the hangers and clamps needed to bolt straight up to the OEM factory location without any modifications required, making it a direct fit, bolt-on replacement upgrade.
Application. This Stainless Works Retro Chambered Cat-Back with X-Pipe is specifically designed to fit the 2015-2017 GT Fastback Mustang with the factory exhaust manifolds installed. Not compatible with convertibles.
