Steeda 304SS Resonator Delete H/X-Pipe (Hex Pipe) – 2015–2026 Mustang GT 5.0L Coyote (S550/S650)

Upgrade your Mustang’s exhaust system with Steeda’s 304 Stainless Steel Resonator Delete H/X-Pipe, engineered for 2015–2026 5.0L Coyote-powered S550 and S650 Mustang GT models. This performance-focused exhaust upgrade enhances sound, boosts performance, and sheds up to 6 pounds of weight—all at an affordable price.

The unique H/X crossover design delivers the best of both worlds, combining the deep rumble of an H-pipe with the high-flow efficiency of an X-pipe. Unlike many aftermarket options, Steeda’s patent-pending system is designed to retain the factory heat shield found on 2018+ GTs without the need for cutting, expanding, or chiseling OE parts.

Crafted from premium U.S.-sourced T-304 stainless steel, this mandrel-bent 2.5" tubing resists the rust and corrosion issues common with 409 stainless or aluminized mild steel. Installation is straightforward, fitting directly between the factory catalytic converters and mufflers, and it’s fully compatible with most aftermarket axle-back exhaust systems. Flush-fit band clamps are included for leak-free connections and allow the pipe to be shortened if needed.

Note: As with all resonator deletes on the market, cutting the OE exhaust pipes is required.
