2015-2019 WRX FA20 Equal Length Header by Perrin

Instantly increase turbo response and add 15-20 wheel horsepower and 20 ft-lbs of torque with the PERRIN Equal Length Headers. This part is perfectly safe to install and does not required an ECU tune.

The PERRIN Equal Length Headers produce smooth and balanced exhaust flow from the heads to the turbocharger, giving you the best of two worlds: quick turbo response as well as more horsepower and torque throughout the entire RPM band. The OEM header has a terrible collector design, restricting exhaust flow.

PERRIN Flanges are CNC machined from 304 stainless steel and counterbored on the back side to make smoother transitions. Flange ports are sized properly to ensure exhaust coming out of the head has a smooth, unobstructed path to the tubes. The ports are not over-ported which would cause gaskets to burn out quickly. The tubes are expanded inside the flanges for a perfect fit and smooth flow of exhaust gases to the tubes.
