Product Description
No Drone ZoneThe PERRIN Axle Back Exhaust features a frequency-eliminating Helmholtz resonator to combat the natural occurring resonance the BRZ exhaust produces. This unique, engineered chamber eliminates the low RPM droning and booming without adding any restriction to exhaust gas flow.
Slash cut tipsThe PERRIN Axel Back Exhaust features a single over-sized 4.5" slash cut exhaust tip which fill the bumper cutout and add a purposeful, race car look.ConstructionPERRIN exhaust systems are made entirely of 304 stainless steel. Other manufactures 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.PowerThis test was done on a 2022 BRZ running a stock ECU tune. We swapped out the rear exhaust section in five minutes and re-dynoed the car to find an additional 3-4 WHP and 3-4ft-lbs of torque.FinishThe PERRIN Exhaust systems come with a brushed stainless steel finish featuring TIG welding for precise, clean welds.
