Description

Upgrade your vehicle with the Invidia catted Downpipe. This particular downpipe features a divorced wastegate flange which will separate the exhaust gas while exiting the downpipe. This design helps promote a smoother exhaust flow which results in more horsepower and torque and reduced turbo lag. The downpipe has also been constructed from 304 stainless steel materials with 3" mandrel bent tubing and will bolt up to any stock replacement catback or factory exhaust system.

This downpipe will also come designed with an extra oxygen sensor bung welded in which will allow you to install a wideband O2 sensor while retaining your factory oxygen sensor intact. With that said, it will also come with an O2 plug in case you are not using a wideband O2.

New hardware and a gasket for the end of the downpipe will be included, please note that a new downpipe gasket is recommended to complete the installation of this downpipe.

Love it

Before getting this downpipe I had the N1 catback installed on my 11 WRX. The catback alone enhanced that nice rumble, but this downpipe brought that rumble a whole new level! Performance gains weren't all that I was hoping for, but they were still noticeable so no complaints there. I've had this downpipe on for just under 2 months now, and I still love it and get a smile on my face every time I start my car.

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!

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.

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: Extra bung plug for wideband sensor   TonyKeoWRX14 2 months ago

    Answer

    What is the socket size to remove the bolt so I can install a wideband sensor for an AEM air/fuel gauge.


    • A: It is either a 14 or 17. Almost positive it is a 14 but it should be among a set of metric wrenches.

  • Q: 2015 STI  Stephandoan 2 years ago

    Answer

    I have everything stock except intake and access port, do I need any adapters or gaskets for this down pipe? Thanks!


    • A: You would need a 3" downpipe to stock catback adapter as well as a replacement donut gasket is recommended. This downpipe does not include the turbo to downpipe gasket so that is recommended. Another thing to consider would be the turbo heat shield, but the stock unit can be trimmed to fit around this bellmouth.

  • Q: Gaskets!  jabad978 2 years ago

    Answer

    With purchasing this downpipe, I'm aware of needing to purchase a brand new gasket for turbo/downpipe but I'm wondering if i also have to purchase a new gasket from downpipe to an 3" aftermarket catback exhaust?? & would it be a donut gasket or regular exhaust gasket??


    • A: It will depend on the size of the midpipe flange on your catback exhaust. If it is a 3" flange, you can use the included 3" 2 bolt gasket. If your exhaust is stock or uses a 2.5" flange, then I recommend getting a 3" downpipe to stock catback adapter and a new donut gasket. This adapter helps prevent leaks and allows you to use the OEM donut gasket.
