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*

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.

Q: Invida N1 fitment Xavier 4 months agoAnswer
I'll going to get the Invidia N1 catback dual exhaust for my 2013 WRX sedan 2.5l, will the be a good set up for it? And if so how much more HP will it give me?
A: Yes you can pair this up nicely with a N1 catback. With a proper tune, you could gain 10 or so horsepower.
