Product Description

Mustang Racing Technologies 3" to 2-1/4" Stainless Steel Off-Road Downpipe for all 2015, 2016 and 2017 EcoBoost Mustangs.

Are you looking for the best combination of both exhaust sound and performance? If so, then look no further than this brand new 3” to 2-1/4” Stainless Steel Off-Road Downpipe from MRT. Not only will it make your 2015-2017 Mustang EcoBoost sound more aggressive, but it will also add some much needed power to the rear wheels! This MRT off-road downpipe is a direct replacement for your factory EcoBoost downpipe.

With Ford introducing the new EcoBoost Mustang to the world, there has been quite a bit of talk around performance modifications for this platform. MRT has jumped head first into engineering high quality performance parts. MRT's CNC mandrel bending technology ensures that their downpipes have smooth bends and precise fit. MRT manufactures all of their EcoBoost downpipes out of the highest grade 304 Stainless Steel right here in the USA at their headquarters.

Features and Benefits:
- Full 304 Stainless Steel Construction
- 3” to 2-1/4” OEM Connection
- Significant HP and TQ Gains
- Much More Aggressive Sound Over Stock
- Reuses Factory Hardware for Installation
- Smooth Mandrel Bends for a Perfect Fit

*Does NOT include catalytic converter.
*This part is not intended for use on public roads or highways (off-road use ONLY!)

Tech Tip: Due to removing the catalytic converter, a custom tune/calibration will be required after installation, NOT included. Although your car will run and drive, it will throw a check engine light and tend to run on the rich side. Prolonged use without a proper tune/calibration could cause engine damage or a catastrophic failure.

If you're looking for the latest styling and performance parts for your Ford Mustang, you have lots of major brands to choose from. However, few offer the same experience and proven results as Mustang Racing Technologies. CJ Pony Parts offers the latest styling and exhaust performance products from MRT, giving you lots of choices from one of the leading and most trusted retailers in the aftermarket.

Order the Mustang Racing Technologies 3" to 2-1/4” Stainless Steel Off-Road Downpipe for your 2015-2017 EcoBoost Mustang from CJ Pony Parts today!

Product Questions

I have a magna flow street full exhaust , would this fit my exhaust and will the check engine come on 

Asked by: ben123
This will fit your exhaust but you will need a custom tune or your check engine light will come on due to removal of the catalytic converter.

I live in North Carolina...would this make the check engine light come on? If so is there something else that I can use to get more power without doing that?

Prolonged use without a proper tune/calibration could cause engine damage or a catastrophic failure. You could use this catted down pipe, http://www.cjponyparts.com/mrt-downpipe-high-flow-catted-stainless-steel-3-to-2-1-4-ecoboost-2015-2017/p/DPMR2/, Although NOT required, a custom tune/calibration is highly recommended after installation, NOT included.

With this do you have to worry about a check engine light being on with no cats?

This requires a custom tune to keep the check engine light off.

MRT Downpipe Off-Road Stainless Steel 3" To 2-1/4" EcoBoost 2015-2017 Video Transcript
By Bill Tumas: We’re here with an MRT off-road downpipe fitting your 2015 EcoBoost Mustang.

An after market downpipe is a great way to pick up horsepower and torque in your EcoBoost Mustang. MRT's downpipe is made of 3 inch mandrel bent 304 stainless steel. It measures a 2-1/4 inch outlet. That means it will work with many after market catbacks, it will work with the stock downpipe or the stock catback will also work with this system. The MRT downpipe is going to be a direct replacement for your factory downpipe and it's going to install using the supplied hardware along with your factory hardware.

Here's a clip from one of our previous videos showing the basics of installing the MRT downpipe on your EcoBoost Mustang.

This downpipe does not have a catalytic converter so it's recommended for off-road use only. A catted version is available for street use. On either downpipe we do suggest the use of a tune when installing.
