Give your 2018-2023 5.0L Mustang GT the signature ROUSH Performance sound, powerful looks, and boosted performance with this ROUSH Performance Cat-Back exhaust system. This 2018-2023 ROUSH Performance Cat-Back exhaust system is constructed of corrosion-resistant 304 stainless steel and is mandrel bent for high-performing airflow. Thanks to hours of R&D, testing, and validation, this ROUSH Performance Cat-Back exhaust system improves flow and reduces back pressure in your Mustang's exhaust system. Along with polished 304 stainless steel tips, this system includes a mandrel-bent x-pipe, mid-pipes, and dual high flow mufflers that improve the sound, performance, and flow characteristics of the Mustang's V8 powerhouse. ROUSH Performance recommends checking your local noise ordinances levels prior to purchase.
A cat-back or similar exhaust system replaces the exhaust piping from a set point, such as the catalytic converter or filter, back to the outlet, routing exhaust gas out from under the vehicle.
