Fits 2015-2023 Ford Mustang EcoBoost and EcoBoost Premium models (2.3L / 3.7L).

Replace the restrictive factory resonator on your S550 Mustang with the Roush Performance Resonator Delete Y-Pipe. This kit is designed to eliminate the factory resonator to produce a deeper, more aggressive exhaust note while improving overall exhaust flow. By reducing back pressure, this Y-pipe helps optimize horsepower and torque output for the 2.3L EcoBoost and 3.7L V6 powerplants.

Constructed from high-grade 304 stainless steel, the 2.5-inch assembly features mandrel-bent tubing to maintain a consistent diameter through every bend, ensuring maximum flow and long-term corrosion resistance. This system is engineered using OEM vehicle CAD data for precise fitment and bolts directly into the factory exhaust location. Pair this with a Roush axle-back kit for a complete exhaust solution.
