Boost HP and TQ with the PERRIN Equal Length Header. Larger primary and secondary tubes deliver 5 WHP on Stage 1 cars and even more on 350+ WHP builds, all without sacrificing turbo response.
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.
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.
Finish
PERRIN Equal Length Header for 2022+ WRX features a brushed stainless steel finish.
Power
Testing on an aggressive Stage 1 Tuned 2022 WRX with typical bolt-ons installed adds 5-10 WHP at the upper RPMS and even more on cars pushing past 350 WHP!
No Tuning Required
Increase horsepower and torque without ECU recalibration or tune! This part is designed and tested to work safely on your vehicle without any tuning required! However, more power can be gained with proper ECU tuning! Confirm any tune or recalibration you add is specific for ALL modifications added to the vehicle.
