It gets the job done. Not the best quality.

Pipe seems decent. The welds look sloppy, especially next to my Nameless Performance cat-back. My tuner pointed out that the cat would be exposed to hight amounts of heat with it being located so close to the turbo. Due to this he said that he has seen some cat failure from this downpipe before. So he said that I probably should have gone with a downpipe that had the cat located lower on the downpipe. Maybe worth spending a few extra bucks for a better design. Overall, I'm happy with the performance gains i've seen out of this and the quality of the welds don't seem to be causing any issues. It is just a piece of piping after all...

Definitely a very well made item. I gave it a high-temp protective coating to prevent rusting and a thermal wrap to lower temps in the engine bay. Installed Invidia's Q-300 exhaust at the same time on my 2015 STI. Great fitment, was able to install alone. I have no doubt my Invidia exhaust system will last a while and handle my current setup that puts 410hp to the wheels at 380ftlbs of torque.

I was lucky enough to install this Invidia Catted Downpipe and the Perrin non resonated quad tip exhaust at the dealership I work at. Total labor time for both products was about 3 hours. Great quality, great value. IMO the combination of both parts gave me exactly what I wanted in loudness and depth.

Love this down pipe!

I installed the Invidia DP two weeks ago and wish I bought this sooner. The difference in power is black and white. Just one tip when in stalling, make sure the wires from the o2 sensor clear the driveshaft . I learned the hard way haha and it set off my check engine light after a week.

Awesome dp, crappy shipping

The dp is awesome. Solid construction, great welds. But when it showed up at my house, the box was destroyed and the bolts kit and gaskets were gone. I called my friends at RSD and they helped me out tho. A+ customer service

  • Q: 2014 wrx with SPT  Sheedmusa17569 3 days ago


    I currently have a 2014 wrx hatchback, will this be a direct fit to my spot catback?

    • A: you will actually need GRM 077044 to ensure a proper seal. The SPT is a 2.5 inch diameter where the Invidia is a 3 inch diameter.

  • Q: Downpipe   Jay 3 months ago


    I installed a invidia catted down pipe on my 2014 subaru wrx hatchback, after a week the check engine light, traction control light came on and the cruise control light start flashing . I already flash this with a stage 2 map on my cobb accessport after the installation. So what went wrong ? Any advice.?

    • A: Ouch, I am not entirely sure this could be a serious issue most likely not caused by the down pipe. I would take the car to Subaru for diagnosis.

    • A: Found the problem. The o2 sensor wire got slice by the drive shaft located just on top of it. Somehow the clip that's holding the o2 sensor wire down came off and the o2 sensor wire got caught by the drive shaft. It also cause one of the fuse that is located under the glove compartment to burn out. It's the blue 15 volt fuse on the very left. There are 2 blue 15 volt fuse in there. I ended up buying a factory o2 sensor in the dealership about $163.00 + tax, and the 15 volt fuse I got it in the fuse box . There are extra fuses in there located at the cover of the fuse box. Maybe I could have bought after market o2 sensor that is way cheaper but it has to be ordered and it will take a couple of days to come in and I wanted to get it done asap. Anyway that is my experience...hope this helps somebody out too. My car is a 2014 subaru wrx hatchback premium. Thanks and God bless everyone.

  • Q: Perrin catback   Dangerdan 4 months ago


    Is there anything else i would need to install this with my perrin cat back on a '13 hatch WRX? Also, what is the difference VS a bell mouth down pipe ( such as COBB) ?

    • A: This will be a direct fit with the Perrin Cat Back. The only difference is the flange in the middle of the bellmouth on divorced wastegate downpipes. It separates the exhaust port from the wastegate door to reduce turbulence.

  • Q: Drone   JAWAMSLEYII90816 5 months ago


    Any concerns with drone with this down pipe on a '14 wrx hatchback?

    • A: It is hard for us to answer questions regarding drone. Most aftermarket exhaust system will have some sort of drone but it seems that everyone has different tolerances to it.

  • Q: invidia Downpipe  jfazekas 5 months ago


    What is the difference between this and Cobbs 3inch downpipes? Is this going to add more power, and will it fit a 2016 sti?

    • A: The 2 downpipes will be similar and have similar power. They will add more power but tuning will be required. This will fit your 2016 STI.
