Product Questions

After installation, will the car be able to run before tuning? because I'd have to drive it to a dyno to get it tuned.

Asked by: cole 96
It will throw a check engine light and you will run the risk of damaging your vehicle. Have the dyno shop install it for you and then dyno it all at the same time without having to drive it without a tune, it's not worth the risk.

Mishimoto Downpipe Off-Road Stainless Steel 3" EcoBoost 2015-2017 Video Transcript
By Bill Tumas: We’re here, with Mishimoto's Stainless Steel Off-Road Downpipe, fitting your 2015 through 2016 EcoBoost Mustang.

An aftermarket downpipe is the easiest way to add horsepower and torque to your EcoBoost Mustang. This Mishimoto pipe is made of three-inch stainless steel, and is fully mandrel-bent bent for an excellent fit on your 2015 through 2016 Mustang EcoBoost. This will be a direct replacement for your factory pipe, but because it's an off-road pipe with no catalytic converter will require a custom tune.

The Mishimoto's two-pipe design makes for much easier installation. Also includes a reducer, so you can hook it up to your factory two and a quarter inch exhaust system, as well as an additional port for adding a Wideband O2 sensor.

This Mishimoto Off-Road Downpipe will work with either stock or aftermarket turbos, and again, with stock or aftermarket exhaust systems, and it's a great way to add horsepower and torque to your EcoBoost Mustang.
