Product Description

The Perrin PSP-EXT-368BR Axle-Back Exhaust is engineered specifically for 2022-2025 Subaru BRZ and Toyota GR86 models. Crafted from brushed 304 stainless steel, this axle-back system features a large 4.5" slash-cut tip that fills the factory cutout, delivering both performance gains and bold visual appeal. Its straight-through design reduces backpressure and generates an estimated 3-4 whp and ft-lb of torque on stock ECU setups.:contentReference[oaicite:3]{index=3}

Built with a Helmholtz drone reduction chamber, this system minimizes low-RPM resonance for a refined sound signature that transitions to a sporty, assertive tone under load. The muffler and connections maintain a true 3" diameter throughout for smooth exhaust flow and sustained performance. Installation is completely bolt-on with OEM or direct-fit mid-pipes. Backed by a 5-year limited warranty, this exhaust delivers both reliability and style.
