Overview

Increase power and torque through quicker turbo response and a more efficient collector design with the PERRIN Equal Length Header for 2015-2021 WRX.

Jump To

Increase Horsepower

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. Dyno graph shows results of a 2015 WRX with typical bolt-ons (3 inch turbo-back exhaust and no ECU tune) where the PERRIN header was the only part changed. This test was performed with an hour between runs.

Properly Designed Collectors

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.

Perfectly Sized for More Horsepower

The PERRIN Equal Length Header uses properly sized tubing that matches the Subaru exhaust port size as well as turbo inlet ports. The header to turbo flange on the PERRIN Equal Length Headers allows for easy port modification to accommodate larger aftermarket turbos.

Flanges & Port Matching

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.
