PRODUCT DETAILS

Overview
Add a sporty sound with the PERRIN Axle Back Exhaust for 2022-2025 BRZ/GR86. Featuring an all stainless-steel design and a 4.5” slash cut tip for added performance and good looks.
Sound
- Our resonated system is designed to have a mellow, pleasing rumble at lower RPMs and light throttle. When driving vigorously, the system transitions into an aggressive tone that every sporty car needs.
No Drone Zone
- The PERRIN exhaust features a frequency-reducing Helmholtz resonator to combat the naturally occurring resonance the GR86/BRZ exhaust produces. This unique, engineered chamber, reduces the low RPM droning and booming without adding any restriction to exhaust gas flow.
Single Slash-Cut Tip
- The PERRIN Axle Back Exhaust features a single oversized 4.5" slash-cut exhaust tip that fills the bumper cutout and adds a purposeful, race car look.
Cutout Plate
- Add a PERRIN Exhaust Cutout Plate to conceal the rear bumper exhaust outlet to provide a smooth and uninterrupted aesthetic when installing the single outlet exhaust system.
Construction & Finish
- PERRIN exhaust systems are made entirely of 304 stainless steel. Other manufacturers may use cheaper 409 stainless steel which will rust and corrode over time. Our brushed 304 stainless steel has the best corrosion resistance and appearance after use.
- The PERRIN Exhaust systems come with a brushed stainless steel finish featuring TIG welding for precise, clean welds.
Power
- This test was done on a 2022 BRZ running a stock ECU tune. After swapping out the rear exhaust section, we put the car back on the dyno and found an additional 3-4 WHP and 3-4 ft-lbs. of torque.
