Invidia Catted Downpipe w/ 2 Bungs Manual
Subaru WRX 2015+
Features & Product Details
RallySport Direct proudly carries a large selection of quality high-performance master-crafted exhaust options brought to you by Invidia.
This is the Invidia Catted Downpipe w/2 Bungs. The factory downpipe is highly restrictive by the nature of the design and begins right after the turbocharger leaving much room for improvement. Invidia really opens up the exhaust flow path with their downpipe by developing a unit that combines a larger piping diameter with smooth bends. This will allow the turbocharger to exhale those exhaust gases with fewer restrictions and turbulence for unobstructed flow right out of the cat-back exhaust system. Because of these reasons, downpipes make for the most popular exhaust upgrade that adds a substantial bump in both horsepower and torque with a great reduction in turbo lag.

REVIEWS & CUSTOMER MEDIA
When I bought my car it had a catless downpipe and it threw error codes. So I replaced the entire exhaust with this downpipe and the R400. It doesn't throw any codes and it sounds absolutely phenomenal.
Invidia catted j-pipe is sounds awesome not too loud but gives a great tone paired with a Cobb catback, install was easy for me
This thing fit perfectly. That being said two of the nuts on the turbo studs had to be torched off. We were able to save the studs but it took an Indy car wrencher on a Saturday with a car lift to do it. I got lucky. This was with an 18,000 mile car. Do yourself a favor. Spend the money on new studs when you buy the gasket and nuts. Replace all of it. When I upgraydde the header I'm going to on principle.
arrived extremely quick, only issue i came across was the top right turbo stud didn’t want to move but after we got that it was a breeze bolted right up
I truly enjoy the sound of this j-pipe. It was not that bad to install. The moment I installed there was a difference in performance. Rally sport really helped me out and the shipping was fast!!!!

A: You could bolt it up, but for an OE type fit and for an easier install, I would recommend a 3inch downpipe to OE style catback adapter like this one: https://www.rallysportdirect.com/part/exhaust-gaskets-and-hardware/grm-077044-grimmspeed-3in-downpipe-to-stock-cat-back-adapter Thanks!

A: From the factory, 2015+ WRXs have 2 02 sensors on the J pipe and you will need 2 bungs to run them both. This J pipe does not come with a plug.
