The PERRIN axle-back exhaust for 2022–2026 Subaru BRZ and Toyota GR86 is a single-side-exit stainless steel assembly featuring a tuned Helmholtz chamber to refine exhaust note and flow at the tailpipe. Intended as a direct replacement for the OEM axle-back section, it provides a finished outlet and acoustic tuning without altering other sections of the factory exhaust layout.
