Invidia has released their new two piece catted and cattless downpipes for the 2015 Subaru WRX. Constructed of CNC mandrel bent 304 stainless steel tube TIG welded to cast stainless flanges, it's easy to see why Invidia has become one of the most popular exhaust brands we sell.
Both the catted and the cattless Invidia downpipes have three O2 bungs. Two for the factory sensors and one for an aftermarket wideband O2 sensor or EGT sensor. Because the catted downpipe uses a very high flowing catalytic converter, both the catted and the catless versions will improve exhaust flow and increase the power output of the FA20DIT WRX.
Installing an Invidia downpipe will require you to have your FA20DIT powered 2015+ WRX tuned in order to avoid check engine lights and limp mode.
Invidia includes gaskets and hardware to connect the two pieces of their downpipe together and to your catback, but does not include new studs or a turbo-to-downpipe gasket.
WARNING: It's common for people while installing these downpipes to end up with broken turbo-to-downpipe studs.
- Tuning is required.
- For off road use only. This is a CARB Regulated part that cannot be shipped into CA.
