Mishimoto - MMDP-WRX-15CAT

Catted Downpipe, fits Subaru WRX 2015-2021

Mishimoto is proud to release the Performance Downpipe for the 2015+ Subaru WRX. The biggest restriction in the stock exhaust system is the downpipe. By installing the Mishimoto Performance Stainless Steel Downpipe, the FA20-DIT exhaust system is able to breathe easier, providing a significant increase in horsepower and torque when tuned. During countless dyno pulls, Mishimoto saw gains of up to 73 whp and 64 wtq with the catted downpipe, Mishimoto tune and Mishimoto Performance Air Intake using 93 octane fuel (see additional images for dyno chart). With the catted downpipe and Mishimoto tune, Mishimoto saw dyno proven gains of up to 57 whp and 52 wtq using 93 octane fuel (see additional images for dyno chart). Above all, this downpipe provides a significant torque improvement in the low end and across the entire power band. The Mishimoto Performance Downpipe provided an extremely aggressive turbo and exhaust tone under acceleration and boost, giving you that aggressive tone you have been looking for!
