FactionFab Axle Back Exhaust

FactionFab Axle Back Exhaust

The Faction Fab OEM replacement axle-back systems are specifically designed for the VA 2015 - 2020 WRX and 2015 - 2018 STI with stock or direct stock replacement mid-pipes. These systems are 100% made in the USA, using American sourced tubing for best quality and manufacturing methods. The systems are made from mandrel bent 16 gauge 304 stainless steel, 3/8" thick laser cut flanges and sturdy 1/2" hangers. All components are meticulously TIG welded by hand to perfection for a long and reliable service life. To finish it off, the systems use slip-on exhaust tips, allowing you to fine tune the position of the tips relation to the bumper.

  1. Overall great buy for the price

    By Dylanflat2.0t March 19, 2022

    It was pretty easy to install with the right tools tho one of the bolts on the clamp broke. The sound on cold start is real nice and loud and after that not to loud. Cruising around d it sounds reall nice but does have a low drone at about 80mph

  2. Overall not impressed for the price.

    By Cody February 19, 2022

    Bought these in the stainless in December. Out of the box one of the tips had some dings in the rolled edge. No huge deal and everything else looked great. Exhaust came with a set of Grimmspeed gaskets to replace the factory ones. That's about where the good ends. Install was simple like any axle back. On my 2020 WRX the driver side fit well but the passenger side was horrible no matter how much I adjusted and refitted. This side was digging the tip into the bumper no matter what I did. The tips for both sides stick out extremely far even when bottomed out. Ended up having to spend another $60 at an exhaust shop cutting the pipes so the tips would sit right and had to cut a notch into the passenger side of the factory Y section to get the placement right for the passenger side tip. Overall would not recommend for this price point when there are proven better fitting brands for similar cost.

  4. Does what it's supposed to do..but

    By Josh November 17, 2021

    The installation was very easy, the only hard parts were getting the factory bolts loose and the mufflers off their hangers, but other than that the process was quick and easy. One issue that I have is that for me, the left side hangs slightly lower than the right, and since the tips aren't welded on they tend to rotate a bit after driving for a while. Other than that, I'm very happy with how it looks and sounds.

  5. Deep, rich tone with good build quality and awesome tips.

    By Dustin June 19, 2021

    I was worried about getting a muffler delete kit, but this system is extremely well-built with clean welds done by hand, a cool placard tack-welded on, and amazing burnt tips that are adjustable. The tone is very deep and has a good rumble to it, while not being obnoxious or having drone. I'm very pleased with this kit and I'd recommend it.

  6. Rusted bolts

    By Baesic December 19, 2020

    Rusted bolts and one side of the exhaust tips didn't fit had to bend part of it and overall sound kinda disappointing

  7. EXCELLENT Fit and finish! Great Customer Service

    By AirWolfe81 December 8, 2020

    First of all, these shipped out super quick, even though they were on back order. When I openend the box I found 2 left side tips. FactionFab quickly responded to me and shipped the correct part to me that same day!!! Excellent Customer service. As for the install, it was a breeze and fit EXACTLY. No need for adjustments or anything. Fit like a glove. The sound is awesome as well. I would recommend these to anyone!!
