Mishimoto is proud to expand their line of 2015+ WRX parts to include the performance 2015+ WRX Downpipe. The biggest restriction in the stock 2015 WRX exhaust system is the downpipe. By installing the Mishimoto 2015 WRX downpipe, the FA20DIT 2015 WRX 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 2015+ WRX catted downpipe, Mishimoto Subaru WRX Tuning Kit, and Mishimoto Subaru WRX Performance Air Intake using 93 octane fuel on the 6-speed 2015+ 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 2015+ WRX (see additional images for dyno chart). Above all, this 2015+ WRX downpipe provides a significant torque improvement in the low end and across the entire power band. 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!
The engineers at Mishimoto designed the 2015+ WRX downpipe as a one-piece design with precision TIG-welded 304 stainless steel. This allows uninterrupted exhaust flow from the 3.5" 4-bolt exhaust flange all the way through the 3.0" downpipe. The engineers also created two different transmission-specific brackets, for the 6-speed manual and CVT, to mount the downpipe to the transmission. To customize the 2015+ WRX downpipe even further, it is offered in either a catted or catless version. Because the engineers know that 2015+ WRX owners commonly like to add wideband O2 gauges, they included an additional O2 sensor bung and plug in an ideal location for aftermarket wideband sensors! To top it off, the 2015+ WRX downpipe includes new turbine housing studs and nuts (which commonly strip), a new turbo outlet gasket, a new 3” 2-bolt flange gasket, and all stainless steel hardware, so you don’t have to worry about rust on your hardware. The Mishimoto Subaru WRX Downpipe is proudly made in the USA and like all of our 2015+ WRX parts comes with the Mishimoto Lifetime Warranty you know and trust.
