Roush Cat Back Exhaust Kit
Unlock the full potential of your non-active exhaust-equipped 2018-2026 Mustang GT with Roush Performance's cat back exhaust system. Designed for a bold, aggressive sound and superior performance, this system enhances your S550 or S650's presence while significantly improving exhaust flow and efficiency. The result is more power and a quicker throttle response. Roush’s cat back exhaust is the ultimate upgrade, offering both striking sound and exceptional function. Featuring the Roush X pipe resonator delete and straight-through muffler design. Designed for a bolt-on installation, this Roush cat back can be installed straightforwardly with basic hand tools, without cutting the factory exhaust system.

Roush Quality
Roush's cat back kit is designed and tested to give your S550 or S650 5.0 the most aggressive sound and performance possible. Featuring mandrel-bent pipes, this helps reduce back pressure and the disruption of airflow by using tubing that is smooth and doesn't neck down. Crafted from high-quality 304 stainless steel, it’s built to withstand the demands of both street and track use, ensuring durability and longevity. The unique straight-through muffler design produces a deep, throaty rumble that reflects the Mustang’s raw power. The 3.5" stylish black quad exhaust tips, stamped with Roush on top, not only add a custom, refined look to your Mustang’s rear end but also enhance the system's acoustics. With an easy, modification-free installation that uses factory hanger locations and mounting points, this kit includes all the necessary hardware and detailed instructions for a seamless setup.
