Roush's X-pipe resonator delete is a great way to get a new and louder sound from your Mustang GT. The resonator delete improves the exhaust flow and reduces backpressure for better performance at high rpm.

Racecar-like sound. An x-pipe provides a more modern sound than an h-pipe and is a great fit for the S550 Mustang. The x-pipe deletes the factory resonator that quiets the exhaust system. This is compatible with both active and non-active exhaust systems and has an even more dramatic sound with an axle-back exhaust. 

High-rpm performance. Exhaust flow is improved at high rpm with an x-pipe, helping your engine run more efficiently and make more power. This is the perfect addition to the Mustang GT and Coyote engine, where the redline is at nearly 8,000 rpm.
