FactionFab Axle Back Exhaust - 2022+ Subaru WRX (Polished Tip)

The Easiest Upgrade for a Better Sound, Look, and Feel

Replace the restrictive factory muffler with FactionFab's high-flow, mandrel-bent axle back exhaust — engineered specifically for the 2022+ Subaru WRX. Optimized for flow, performance, and weight reduction, installation is quick and straightforward with only basic hand tools required.

Built from premium 2.5" CNC mandrel-bent 304-L stainless steel tubing with robust 3/8" laser-cut stainless flanges and hand TIG welded for maximum durability. Directly replaces the stock muffler section (not compatible with SPT exhaust systems). All hardware and gaskets included for a true bolt-on install.

The polished tip features double-wall construction with 3.5" quad styling for an aggressive, custom look.
