PERRIN 22-26 Subaru BRZ / Toyota GR86 Axle Back Exhaust SS (Single Side Exit w/Helmholtz Chamber)

Reduce low RPM droning without any restriction to exhaust gas flow with the PERRIN Axle Back Exhaust for 2022-2023 BRZ/GR86. Featuring an all stainless-steel design and 4.5” slash cut tips for added performance and good looks. The PERRIN exhaust features a frequency-reducing Helmholtz resonator to combat the naturally occurring resonance the BRZ exhaust produces. This unique, engineered chamber, reduces the low RPM droning and booming without adding any restriction to exhaust gas flow. The PERRIN Axel Back Exhaust features a single oversized 4.5" slash cut exhaust tip that fills the bumper cutout and adds a purposeful, race car look. 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. The Perrin 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.
