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 BRZ exhaust produces. This unique, engineered chamber, reduces the low RPM droning and booming without adding any restriction to exhaust gas flow.

SLASH CUT TIPS
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.

CONSTRUCTION
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.

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.

FINISH
The PERRIN Exhaust systems come with a brushed stainless steel finish featuring TIG welding for precise, clean welds.
