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 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.
