Introducing ATP's 3" Modular Downpipe for your 2015 Ecoboost Mustang! Your S550's exhaust is by far one of the most restrictive systems on your Mustang, especially its downpipe. The mediocre 2.5" system leaves you hanging, with less performance and overall disappointment. The factory pipe also causes massive back pressure, choking your turbo and hindering your power.

ATP's 3" Modular 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, just look at the dyno sheets! This downpipe was engineered to be compatible with your stock exhaust system and includes an adapter for just that. The benefit of the fully modular system is that you can upgrade your exhaust and turbo in the future, separately. The adapters that come with this system let it work with stock, all you have to do is remove it for an upgrade.

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!
