PRODUCT DESCRIPTION
Mishimoto continues to expand its line of performance exhaust 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 piping. This downpipe will easily outperform the restrictive stock piece and allow your Mustang EcoBoost to make maximum horsepower and torque. With this downpipe installed on our EBM Mustang and the ECU re-tuned with a more aggressive setup, the engine made an additional 65 whp and 108 wtq over the catted downpipe. With the Mishimoto catless downpipe installed, we saw additional gains of 9.8 whp and 8.3 wtq over the catted model, making this an excellent choice for those looking for maximum power. The Mishimoto downpipe was also designed to be easy to install and adaptable to many exhaust setups. We know there are many cat-back exhaust options out there, and the included 3.0" to 2.25" adapter allows easy connection to the stock 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 with a custom exhaust or the upcoming Mishimoto Cat-Back exhaust to create a full 3" downpipe/mid-pipe combination. The two-piece downpipe design allows for easier installation without having to wrestle a large, bulky pipe into place. The Mishimoto downpipe comes with all the clamps and flanges needed for installation and mates perfectly to the stock turbo gasket, making the purchase of additional gaskets or hardware unnecessary! Like all our EcoBoost Mustang parts, this downpipe comes with the Mishimoto Lifetime Warranty. Direct fit for the 2015+ Ford Mustang EcoBoost with optional catalytic converter. 3" from turbo to V-band, 3" to 2.25" at exhaust adapter end. Compatible with manual and automatic transmissions. 304 stainless steel design includes an additional O2 sensor bung. Mishimoto Lifetime Warranty.
