Features & Product Details
RallySport Direct proudly carries a great selection of quality performance exhaust modifications brought to you by Faction Fab.
Here, you are looking at the Faction Fab Axle-Back Exhaust System. This is a quick and easy way to increase the performance, looks, and sound of your vehicle. These are direct replacements for the heavy and aesthetically unpleasing stock mufflers with muffler deletes. Installation can be performed in a matter of minutes using simple hand tools.
The Faction Fab OEM replacement axle-back systems are specifically designed for the GR 2011-2014 WRX and 2008 - 2014 STI HATCHBACKS 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 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 in relation to the bumper.

This axle back is amazing. It looks great, and has beautiful welds. I have the cobb catted downpipe and with this combo, you cant go wrong. It sounds just as good as it looks. My ONLY complaint is that I had to file down the inlet of the tips that connect to the Y-pipe in order for them to fit. Also lining them up perfectly was challenging, only because I am OCD.
I installed this axle back/muffler delete on my 2008 Subaru WRX STI and what a difference it made to the sound of the exhaust! With the stock exhaust the driving experience was pretty dull and you could not hear it inside the car at all. After the quick install of this axle back the exhaust was brought to life. There is no drone on the freeway, just a nice deep tone of the sweet sound of the boxer engine. If I press the throttle just right I can get it to burble a little. As a added bonus it weighs less than half of the factory muffler.
