The 02-07 Subaru WRX PERRIN Equal Length Headers use 1.5" primary tubing that is expanded at the flange to fit the Subaru exhaust port size. This size of tubing is perfectly designed for cars up to 400WHP. For those looking to go way beyond 500 wheel horsepower, opt for the big pipe equal length header. The equal length design of the PERRIN header, produces smoother more balanced exhaust pulses flow from the head 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 mate with an OEM or aftermarket up-pipe, as well as any rotated turbo kits compatible with the factory header. Because of it equal length design, the PERRIN header will alter the tone of your exhaust. The exhaust pulses from the engine are equalized and spread out producing a smoother, more refined sound. Some describe the sound to be EVO like similar to an inline four cylinder engine exhaust.
