Mishimoto continues to expand on our line of performance exhaust system components! After months of development and testing, 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 over stock 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 Mustang EcoBoost exhaust or most aftermarket cat-back exhausts with the stock-sized 2.25" mid-pipe. The adapter can also be omitted, so the downpipe has a 3.0"" V-band outlet to mate up to a custom exhaust, or the upcoming Mishimoto Mustang EcoBoost Cat-Back Exhaust to make a full 3" downpipe / mid-pipe combination. The two-piece EcoBoost Mustang downpipe design allows for an easier installation without wrestling a large bulky pipe into place. The Mustang EcoBoost downpipe comes with all of the necessary clamps and flanges you’ll need for installation, and mates perfectly to your stock turbo gasket, making the need to purchase additional gaskets or hardware unnecessary! Like all of our EcoBoost Mustang parts, this downpipe comes with the Mishimoto Lifetime Warranty!
