Product Description

The Roush 422119 Resonator-Delete H-Pipe is engineered for owners of the 2015-2025 Ford Mustang GT with the 5.0 L V8. This upgrade replaces the factory resonator section with a mandrel-bent stainless-steel H-pipe, offering enhanced exhaust flow, a deeper and more aggressive tone, and improved performance potential - especially at higher RPMs.

Installation is straightforward thanks to the design that retains your factory catalytic converters and mounting hardware, minimizing modifications. The improved exhaust flow and reduced back-pressure help unlock the full potential of the stock or modified exhaust systems. It's an effective way to refine both sound and performance without a full exhaust system replacement.

This part is ideal for Mustang GT drivers seeking a meaningful tone and performance upgrade. Before installation, verify your vehicle year, engine (5.0 L V8) and existing exhaust configuration to ensure compatibility.
