Product Details

This ROUSH H-pipe assembly is what you get when you want to ditch the factory resonator on your 2015-2023 Ford Mustang GT. It's a direct replacement for the stock piece, designed to bolt right up and give your 5.0L V8 that deep, aggressive exhaust note you're looking for. It's a straightforward way to change the sound of your Mustang without affecting the check engine light.

Built from 2.5-inch mandrel-bent stainless steel, this H-pipe is made to handle the exhaust flow from your GT. Mandrel bending means the pipe keeps its shape under stress, ensuring consistent exhaust flow and less back pressure. This can help your engine breathe a little easier, potentially leading to improved horsepower and torque. ROUSH uses OEM vehicle CAD data to make sure this H-pipe fits precisely where your factory resonator used to be.

If you're aiming for that race-inspired exhaust tone and a bit more performance from your Mustang GT, this ROUSH H-pipe is a solid option. It's designed for a straightforward installation, making it an accessible upgrade for many owners.
