PERRIN Performance Equal Length Header Subaru 2002-2014 WRX / 2004-2021 STI
PSP-EXT-055
Create a smooth-sounding exhaust note while increasing horsepower and torque with the PERRIN Equal Length Header. Available in both Standard 1.5" or 1.625" Big-Tube Primaries.
The PERRIN Equal Length Header comes with collectors that have been designed for better exhaust flow while allowing the headers to be constructed with increased accuracy. The improved exhaust flow and more precise construction increase power and reliability, while the low-profile design allows for excellent ground clearance.
The equal length design of the PERRIN 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 the factory up-pipe, our header will also mate with an aftermarket up-pipe that fits the factory header and turbo, as well as any rotated turbo kits compatible with the factory header.
