Quick Performance and Sound Upgrade
The Faction Fab Axle-Back Exhaust System offers an easy and effective way to improve your vehicle’s sound, appearance, and performance. Designed as a direct replacement for bulky and restrictive factory mufflers, these muffler deletes not only reduce weight but also enhance exhaust tone. Installation is fast and simple with basic hand tools, making it a great upgrade for track builds, rally cars, overlanders, or daily drivers looking for a more aggressive exhaust note.

 

Precision-Built for Quality and Fitment
Designed specifically for the 2011–2014 Subaru WRX and STI (GV chassis), the Faction Fab OEM replacement axle-back systems pair seamlessly with factory or direct-fit mid-pipes. Proudly manufactured in the USA using American-sourced materials, each system features mandrel-bent 16-gauge 304 stainless steel tubing, 3/8" laser-cut flanges, and durable 1/2" hangers. Every component is hand TIG-welded for superior strength and longevity. The exhaust also includes adjustable slip-on tips, allowing precise alignment with the rear bumper for a clean, custom finish.
