Mishimoto Downpipe Catted (15-17 Mustang Ecoboost)

Mishimoto has released the stainless steel downpipe for the Ford Mustang EcoBoost! This downpipe was designed with maximum exhaust flow in mind, using 3" mandrel-bent stainless steel tubing. This downpipe will easily outflow the stock restrictive piece, and allow your EcoBoost Mustang to make maximum power and torque! With this Mustang EcoBoost downpipe installed on our EBM Mustang and the ECU re-flashed with a more aggressive tune, the engine was able to make an additional 65 whp and 108 wtq overstocks with our catted downpipe installed. With the Mishimoto catless downpipe installed, we produced additional gains of 9.8 whp and 8.3 wtq over the catted model, making this a great option for those seeking maximum power output. The Mishimoto Mustang EcoBoost downpipe was also designed to be easy to install, as well as adaptable to many exhaust configurations. We know there are many choices out there for cat-back exhausts, and the included 3.0"-2.25" adapter allows easy mating to the stock
