Improved Flow for Increased Power. The catted X-Force 3-Inch Down Pipe is designed to improve the Mustang's exhaust flow to provide additional horsepower and torque. It features a non-restrictive, mandrel-bent design equipped with a high-flow catalytic converter. Note that this down pipe will not fit the factory cat-back and an X-Force cat-back is recommended for direct-fit bolt-on installation.

More Aggressive Exhaust Sound. The X-Force 3-Inch Down Pipe also improves exhaust sound with the increased exhaust flow. The exhaust sound can be further tuned with the use of aftermarket cat-backs.

Durable Stainless Steel Construction. The X-Force 3-Inch Down Pipe is designed and dyno-tested for maximum performance. It features CNC mandrel-bent pipes and high-quality construction for superior performance and style.

Bolt-On Installation. The X-Force 3-Inch Down Pipe uses the factory mounting points for easy installation. However, it's designed to be direct-fit to X-Force cat-backs and cutting may be required when used with other aftermarket cat-backs. It will not fit the OE cat-back.

No Tune Required. The X-Force 3-Inch Down Pipe is specially designed to function without a computer tune. However, a tune is highly recommended after modifying the exhaust to ensure optimum performance.

Not CARB Certified. The X-Force 3-Inch Down Pipe is not CARB certified at this time and is not intended for installation or use in California or other states adopting California emission control standards. Note that this down pipe is intended for track and off-road use only.

Application. The X-Force 3-Inch Down Pipe with high-flow catalytic converter is designed to fit 2015 to 2019 Ford Mustang EcoBoost Models.

Technical Note. This down pipe will not fit the factory cat-back. An aftermarket cat-back is required to complete the installation.
