This is the easiest and most cost-effective way to make your 2022+ Subaru WRX sound better, look great, and perform at its best. Replace the restrictive factory muffler with FactionFab's high-flow, mandrel-bent axle back exhaust system. Engineered specifically for optimal flow, performance, weight reduction, and precise fitment, installation is quick and straightforward, requiring only basic hand tools.
FactionFab axle back exhaust systems feature premium 2.5” CNC mandrel-bent 304-L stainless steel tubing, robust 3/8” laser-cut stainless-steel flanges for a perfect fit-and-seal and are hand TIG welded for maximum durability and reliability. These exhausts directly replace the stock muffler section (note: not compatible with SPT exhaust systems), and each kit includes all necessary hardware and gaskets for a true bolt-on installation.
Personalize your WRX with multiple tip color options, including polished, burnt, or black stainless steel. The tips feature double-wall construction with 3.5” quad styling, providing an aggressive, custom look.
