A decat downpipe is a component of the exhaust system of a FORD FOCUS 1.5 that replaces the function of the catalytic converter. It replaces the pipe that usually connects the exhaust system to the turbo or engine manifold. By installing a decat pipe, you can increase your vehicle’s horsepower. The decat pipe has a full 57mm bore, which provides seamless flow and full power for all 100bhp, 125bhp, and 140bhp engines, while the OE pipe has significant restrictions. Installing a decat downpipe won’t reduce power, and it won’t cause any immediate or long-term running or engine problems. The Ford Focus 1.5 EcoBoost is one of the most popular compact cars on the market and a strong favorite for the younger generation of drivers. Our experts have witnessed significant improvements of up to 175 horsepower while tuning these vehicles, thanks to countless late-night hours spent developing our specific display car.
