Quick Overview

Description:
Mishimoto is proud to release the performance Subaru WRX downpipe for the 2015-2019 models. The biggest restriction in the stock exhaust system is the downpipe. By installing the Mishimoto WRX downpipe, the FA20DIT 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 Subaru WRX Tuning Kit, and Mishimoto Subaru WRX Performance Air Intake using 93 octane fuel on the 6-speed WRX (see additional images for dyno chart). With the catted downpipe and Mishimoto Subaru WRX Tuning Kit, Mishimoto saw dyno proven gains of up to 57 whp and 52 wtq using 93 octane fuel on the 6-speed WRX (see additional images for dyno chart). Above all, this downpipe provides a significant torque improvement in the low end and across the entire powerband. The Mishimoto 2015 WRX downpipe provided an extremely aggressive turbo and exhaust tone under acceleration and boost, giving you that aggressive tone you have been looking for!
