The Torque Solution stainless axle-back exhaust is a direct-fit rear section for Subaru WRX (2015–2025) and WRX STI (2015–2021) applications. Constructed from stainless components and designed to match factory routing and mounting, this axle-back replaces the rear muffler section to refresh fitment and deliver a more defined exhaust note while retaining bolt-on installation simplicity.
