Twisted Steel Performance. Your 2015-2020 EcoBoost Mustang has more going on under the hood than most may realize, but there's an awful lot you can do to make it even better. For starters, you can put in this aFe Race Series Twisted Steel Down-Pipe - Off-Road. This powerful, mandrel-bent 3" pipe can deliver increased performance over your stock down-pipe, increasing both horsepower and torque.

Race Track Roar. This down-pipe delivers race-track only sound for intimidation of others to your satisfaction. The aggressive roar you hear is just a shadow of performance to come.

Direct Stat Upgrade. Providing up to 13 extra horsepower and up to 15 ft. lbs of torque, just replacing this simple down-pipe is enough to make a noticeable difference in your Mustang.

Durable, Flow-Free Construction. The mandrel-bent 304 Stainless Steel used to craft this downpipe creates the maximum amount of airflow possible over stock pipes, while also being incredibly resistant to corrosion and cracking. The joints are TIG-welded for maximum support and a solid construction feel throughout.

Installation. This is a pretty involved job, so having access to a car lift a buddy, and some hand tools is recommended. This is a RACE-ONLY modification, meaning that driving this vehicle on any normal highway is illegal. This is for off-road use only. Mechanical expertise is required for removing the old stock pipe, so please have this installed professionally if you don't think you can do it yourself.

2-Year Warranty. aFe provides a two-year warranty on this down-pipe, protecting against manufacturer and material defects. Check out their full warranty for more details.

Application. This aFe Race Series Twisted Steel Down-Pipe - Off-Road is designed to fit 2015-2020 Ford Mustang EcoBoost models. Ensure correct model before purchase.
