Description
Aggressive, Race-Inspired Sound. Turn everybody’s heads not just with the impressive appearance of your Mustang GT Fastback, but also with a loud and aggressive roar delivered by this Roush Cat-Back Exhaust. With two high-flow mufflers, an integrated mid-pipe, and X pipe, you’ll get significant performance boosts and a race-inspired growl that will make your Mustang sound as powerful as it looks.
Reduces Backpressure to Increase Horsepower. This cat-back exhaust system is engineered to optimize air flow in order to reduce backpressure and therefore increase horsepower and torque. The integrated mid-pipe and X-pipe further increases the performance gains. They work together to smooth out the exhaust flow, make the engine more efficient, and deliver a raspy exhaust sound. The X-pipe also helps deliver more power in terms of RPMs.
Mandrel-Bent 304 Stainless Steel. Roush constructed this cat-back exhaust system out of 304 stainless steel to ensure maximum toughness, long-lasting durability, and a lightweight structure. Using 304 stainless steel also means that this exhaust kit has excellent corrosion and temperature resistance. Moreover, the pipes are mandrel-bent to achieve smooth and uniform curves, which result in a non-restrictive air flow that boosts your Mustang’s performance and sound output.
Polished Surface Finish. For an attractive finish with a subtle shine, the main components of this cat-back exhaust kit have been surface-polished. This process enhances the corrosion resistance of the steel and at the same time removes any impurities that may have been left after the forming process. The tips, meanwhile, are chrome-flashed for a high-shine finish that resists wear-and-tear.
No-Weld Installation. This exhaust assembly doesn’t require any welding or drilling prior to installation. All you need are basic hand tools and the enclosed mounting hardware. Following the instruction manual, you can complete installation in approximately 2 hours.
Application. This Roush Cat-Back Exhaust kit can be installed on all 2015-2017 models of the Ford Mustang GT Fastback.
