Description

The CV Fab CVF 3" Stainless Steel Catted Downpipe is engineered to unlock the hidden performance potential of your turbocharged EcoBoost Mustang. By facilitating more efficient airflow directly from the turbo, this direct bolt-on replacement downpipe helps increase horsepower and torque. It features a 200-cell high-flow catalytic converter, ensuring emissions compliance for off-road use while maintaining a more aggressive exhaust note compared to the stock unit. Constructed from premium 3" T304-grade stainless steel tubing, this downpipe offers superior strength and corrosion resistance. The 100% mandrel-bent piping ensures smooth bends throughout, optimizing exhaust flow for maximum performance gains. It is fully TIG welded for durability and comes with a CVF Lifetime Warranty. This downpipe is designed to fit both automatic and manual 2015-2022 EcoBoost Mustangs. It can be installed on both OEM and aftermarket 3" cat-back exhausts, with a 3" to 2.25" adapter included for connection to the factory system. Please note that this product is intended for off-road use only, is not CARB certified, and is not legal for use in California or other states adopting California emission standards. It is not legal for use on pollution-controlled motor vehicles and is not intended for highway use.
