Racecar Quality Expansion Joints

PERRIN headers use high-quality expansion joints with thermal liners to protect them from extreme heat and stand out from others on the market.

Heat Management

PERRIN Headers are designed to fit seamlessly under the OEM heat shield. Retaining the OEM heat shield is crucial for maintaining proper oil temperatures and ensuring constant power delivery.

The Design

The PERRIN primaries and secondaries are about 14% larger than the stock header, producing smooth and balanced exhaust flow from the heads to the turbo without sacrificing bottom-end power.

The Finish

PERRIN Equal Length Header for 2022+ WRX features a brushed stainless steel finish.
