Perrin Equal Length Header for 2015-2017 WRX

Increase power and torque through quicker turbo response with the PERRIN Equal Length Header for 2015-17 WRX.

SubiSpeed Installation / Overview Video


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 HP

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.


FINISH

PERRIN headers feature a brushed stainless steel finish.

5 Year Warranty

PERRIN Performance warrants to the original purchaser that all PERRIN products will be free from defects in material and workmanship within a sixty (60) month period from the date of purchase.

Off Road Use Only

This product is legal in California only for racing vehicles which may never be used upon a highway. Check your local and federal laws prior to installation.

Warranty Exclusions

We will not warranty any exhaust part that fails or has warped flanges with header wrap installed. While header wrap protects the engine from heat as well as provides some performance benefits, it greatly reduces the life of any stainless steel part. Header wrap greatly increases the rate of corrosion (even stainless steel corrodes), added to that the actual temperature of the metal is much hotter, reducing its lifespan even further. Operation of vehicle without installation of splash guard will void warranty.

We will not warranty any flanges that are warped away from the weld if any aftermarket gaskets are used. Only OEM Subaru gaskets are to be used on this PERRIN Exhaust part, with the exception of downpipes for turbo kits. Subaru provides the proper crush gasket that still becomes flat when tightened (or over tightened) in comparison to aftermarket gaskets which can have a crush ring that is too thick, causing a hot-spot in the middle of the flange. These will warp the flanges of your PERRIN exhaust part, causing a permanent exhaust leak that will not be fixable with a new gasket.
