Introducing ATP's 3" Downpipe for your 2015 Ecoboost Mustang! One of the most restrictive parts on your Ecoboost Mustang is its downpipe, leaving you with less performance and disappointment. The factory downpipes 2.5" diameter is wimpy when compared to ATP's wide open downpipe! The factory pipe also causes massive back pressure, choking your turbo and hindering your power.

ATP's 3" Downpipe lets exhaust gases flow smoothly, reducing back pressure and allowing your turbo to generate more boost pressure for big performance gains. With the right tuning, you can easily get noticeable gains in horsepower and torque. This downpipe was engineered with stock-style reducer flanges that perfectly fit your S-550's factory cat-back system and turbo with no modifications necessary.

The ATP 3" Downpipe is manufactured from high quality T-304 Stainless Steel, so you can be sure it's durable and resistant to corrosion. The piping goes through a mandrel bending process to ensure smooth & precise bends to maximize exhaust flow. This downpipe removes your restrictive catalytic converter for completely unrestricted exhaust flow and thus is recommended for off road applications only. So if you're looking for a downpipe that bolts to the factory exhaust and increases performance, this is the way to go!
