Mishimoto is proud to release the performance Subaru WRX downpipe for the 2015+ models. The biggest restriction in the stock exhaust system is the downpipe (or "J-pipe"). 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. Above all, this downpipe provides a significant torque improvement in the low end and across the entire power band. The Mishimoto 2015 WRX downpipe produces 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 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. Because the engineers know that 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.
This downpipe cannot be used with the stock ECU programming. It is required that the customer is able to retune the vehicle's ECU after installing the downpipe.
Because this product replaces/removes an OEM emissions control device we must state that this product is for offroad use only.
Available for all 2015+ WRX. Choose manual transmission or CVT-equipped car, and between catted or catless design.
