Perrin Performance announces their new E4-Series Equal Length Header for the 2002-2014 Subaru WRX / 2004-2016 Subaru WRX STI. The new Perrin E4-Series Equal Length Header comes with collectors that have been designed for better exhaust flow while allowing the headers to be accurately constructed. The improved exhaust flow and more precise construction increase power and reliability. The new E4-Series also has a low-profile design, allowing for lots of ground clearance.

Equal Length Design

The equal length design of the Perrin E4-Series Header produces smooth, balanced exhaust flow from the heads to the turbocharger giving you the best of two worlds: quicker turbo response as well as more horsepower and torque throughout the entire RPM band. While designed to fit to the factory up-pipe, our header will also mate with an aftermarket up-pipe that fits factory header and turbo, as well as any rotated turbo kits compatible with the factory header.

Perfectly Sized

You won't see grossly over-sized tubing to make our header "look" impressive; this just slows exhaust gas flow and reduces response. This header uses 1.5" primary tubing that is expanded at the flange to fit the Subaru exhaust port size. This size tubing is perfectly designed for cars up to about 400 wheel horsepower.

Flanges and Port Matching

Perrin Flanges are CNC machined from 304 stainless steel and counter-bored on the backside for 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.

Note: 2.0L WRX engines will need the 2.5L STI oil pan install kit.
