Description
The Invidia Catted Downpipe features a Divorced Wastegate and cat, this will separate the exhaust gas exiting the downpipe, creating a smoother exhaust flow, thus resulting in more HP and Torque. All this while keeping the exhaust fumes clean and safe for the environment.

The downpipe is constructed of 304 stainless steel 3" mandrel bent tubing and bolts up to any stock replacement catback or stock unit. New Downpipe Gasket recommended for purchase with this downpipe.

This downpipe also has an extra oxygen sensor bung welded in so you can install a wideband oxygen sensor and keep the stock one intact. It comes with a plug installed so you don't have to worry about not having one.

Happy Happy Happy

I ordered this Downpipe along with the N1 Dual Exit Exhaust to take my 2013 WRX Stage 2. Quality wise, it was beautiful straight out of the box. Way better looking and craftsmanship than the OEM downpipe. As far as installation I have access to a lift and we did the installation in around 2 hours. Removing the stock downpipe is difficult at times (removing the stock heat shield and removing turbo bolts), so you're going to need PB Blaster and a breaker bar. The new Downpipe bolted up easily and was a clean fit with the N1. I then flashed my car with the Cobb Stage 2+ OTS map and my car feels like a whole new machine. 5th gear has become a passing gear and the car pulls hard in 2nd and 3rd. EBCS and Pro-Tune are in the immediate future to get the car's full potential!

*You May Need To Port Your Internal Wastegate*
BlueWrx 6 months ago
First off let me say that I have a 2010 wrx with the stock vf52 turbo. Install was a breeze. Everything lined up and bolted right in. Don't forget to buy the gasket from the turbo to the down pipe, and if you are going to the stock cat back you will need a 3" to 2.5" adapter and the OEM donut gasket. RSD has all these parts. Now to the unfortunate part. Upon installation and flashing a stage 2 OTS map from Cobb, I was getting CEL code P0244 which is essentially "overboost". The waste gate can't get enough air out and results in boost creep. Long story short I took my car down to Cobb, they ported the internal waste gate on the turbo and BAM. Issue resolved. Now I'm off to find a nice canyon.

I currently have this on my 09 WRX and going stage 2 was definitely worth it. Previous to installing this I had the invidia n1 catback and this greatly improved the sound and performance. I'd recommend this + the N1 + AccessPort.

Amazing is all i can say

Got this downpipe today. Installed it in about 2 hours. The old downpipe is a pos so that was the longest part. Bolted up very nice installed the stage 2 ots map and the difference is night and day. Sounds amazing now so much better. A big step in speed and power. So satisfied with the quality of this product. If you are on the edge buy it you will not be disappointed.

    Answer

    Is a turbo to downpipe gasket neccessary and how long does installation usually take i a have the indivia n1 catback already on

  • Q: What other parts are neccessary   Paradise_17 2 months ago

    Answer

    So i have a 2010 wrx with an indivia n1 catback and currently dont have a donut gasket ethier but have the stock downpipe to 3 in. Catback. Adapter. What else would i need to make my install smooth ?


    • A: This downpipe will mate perfectly to your already existing catback. You will not need the catback adapter any longer. All you need is a 3 inch 2 bolt exhaust gasket which is included in this kit.

    Answer

    Im currently putting down 430whp with a invidia catless pipe but its too loud. What WHP would i expect to drop by buying and installing this catted version roughly.?


    • A: Catted down pipes contain high flow catalytic converters and offer just as much performance as catless down pipes. If there happened to be a loss in power, it wouldn't be substantial enough to tell.
