Description
Upgrade the sound, appearance, and exhaust flow of your 2022+ Subaru WRX with the FactionFab Axle-Back Exhaust featuring aggressive 3.5-inch quad black chrome tips. Designed as a direct replacement for the restrictive factory muffler section, this axle-back system provides an effective and cost-conscious way to enhance your WRX without replacing the complete exhaust system.
The system is constructed from premium 2.5-inch CNC mandrel-bent 304-L stainless steel tubing, designed to provide smooth exhaust flow while delivering excellent strength, durability, and corrosion resistance. CNC mandrel bending maintains consistent tubing diameter through the bends, helping optimize exhaust flow and overall system performance.
For precise fitment and a dependable seal, FactionFab uses robust 3/8-inch laser-cut stainless-steel flanges. The exhaust assembly is hand TIG welded for clean, strong welds and long-term reliability, making it suitable for both street and performance-oriented applications.
The system is finished with 3.5-inch double-wall quad black chrome exhaust tips, giving the rear of the WRX a more aggressive and distinctive appearance. The dark tip finish complements the WRX styling while providing a premium custom look.
Installation is designed to be straightforward and can be completed using basic hand tools. The axle-back exhaust directly replaces the OEM muffler section and includes the necessary hardware and gaskets for a convenient bolt-on installation.
Please Note: This axle-back exhaust is not compatible with Subaru SPT exhaust systems.
