Roush Mustang Cat-Back Exhaust Systems
Roush Mustang cat-back exhaust systems feature an aggressive race-inspired tone, style, and performance. These exhaust systems also improve flow and reduces back pressure with mandrel-bent tubing. The cat-backs are constructed of corrosion-resistant 304 stainless steel—and mandrel-bent for high-performance airflow. Systems include high-flow mufflers, integrated mid-pipes, and X-pipe, along with 304 stainless steel tips. Give your 5.0L Mustang GT the signature Roush performance sound, with powerful looks, and boosted performance with a Roush Mustang cat-back exhaust system.
