WRX Catted Downpipe/J-Pipe
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. 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 WRX downpipe even further, it is offered in either a catted or catless version.
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, so you don't have to worry about rust on your hardware. The Mishimoto Subaru WRX Downpipe is proudly made in the USA and comes with the Mishimoto Lifetime Warranty you know and trust.
After further testing, we found that only one stock boost pill needs to be left in the compressor vacuum line. The pill in the wastegate vacuum line needs to be removed. This means that the two boost pills we current include need to be removed.
If you are installing the Mishimoto catted downpipe and Mishimoto EcuTek tune/calibration you must remove the stock boost pill in the wastegate vacuum hose. The Mishimoto tune/calibration has been optimized to work with this combination and will prevent boost spikes. The hose which requires this modification is next to the wastegate actuator. The boost pill can be easily removed and replaced with a screwdriver or pliers.
