Product Overview

MRT Down-pipe 15+ Mustang Ecoboost

Your new Mustangs looks great, and sounds better, but as enthusiasts, we know that good isn't enough. The MRT Down-pipe designed for the 2015 EcoBoost Mustang will provide you with horsepower and torque gains, an increase in fuel economy as well as additional depth to your Mustangs exhaust note! Engineered by MRT to take the place of the OE catalyst and intermediate tubes, this down-pipe is a direct bolt-in upgrade, requiring no cutting or welding to install. 

The MRT Down-pipe free's up as much back-pressure as possible, without having to replace the entire cat-back. Meaning you can still see performance gains without losing the mild tone of the stock mufflers and mid-pipe. The Off-road option replaces the factory down-pipe and catalytic converter with a strait through 3" 304ss exhaust pipe for optimum hp, tq and quality.  MRT also offers two additional catalyst options: our High-flow system (Performance cat) which provides increased flow over the stock catalyst, and our Max-flow system (Race cat) which provides the highest possible flow without removing the catalyst all together.

MRT's CNC mandrel bending technology ensures that all MRT exhaust systems have smooth bends and precise fit. MRT manufactures all of our exhaust out of the highest grade 304 Stainless Steel right here in the USA at the MRT Headquarters. We stand behind the quality of our exhaust systems with an industry leading LIMITED LIFETIME WARRANTY!

This MRT Down-pipe requires no modifications to your 2015 EcoBoost Mustang, meaning this is a direct bolt-on part. MRT recommends a custom calibration whenever replacing the factory catalyst pipe to optimize performance. MRT can provide custom tuning that will greatly improve the performance of your Mustang.
