Perrin Subaru BRZ Toyota GR86 Cat-Back Exhaust

Upgrade your Subaru BRZ / Toyota GR86 with the Perrin Cat-Back Exhaust System, designed to enhance exhaust flow, sound and the overall driving experience of these lightweight rear-wheel-drive sports cars.

The system uses a 3-inch midpipe and a Helmholtz resonator engineered to reduce low-RPM drone while maintaining a sporty and refined exhaust tone. During light throttle and low RPM, the system delivers a controlled rumble, while harder acceleration brings out a more aggressive character.

Constructed from 304 stainless steel with a 4.5-inch slash-cut exhaust tip, the Perrin Cat-Back combines durability with a distinctive performance appearance. Perrin also reports a gain of approximately 3–4 WHP and 3–4 ft-lb of torque on a 2022 Subaru BRZ with the stock ECU calibration.

The system is designed for a wide range of Subaru BRZ and Toyota GR86 applications, with Perrin listing compatibility across model years from 2013 through 2026.

For enthusiasts looking to improve Boxer Sound, Exhaust Flow, Performance Character and Driving Experience, the Perrin Cat-Back Exhaust System provides a balanced upgrade for both daily driving and spirited use.
