The Perrin FA20 turbo header drastically improves on the factory unit, producing smooth and balanced exhaust flow from the head to the turbo. This gives you the best of both worlds, with increased turbo response and more torque and horsepower through the whole power band. Instantly increase turbo response and add up to 20 whp and 20 ft-lbs of torque with the Perrin equal length header. 

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 header allows for easy port modification to accommodate larger aftermarket turbos.

This header does not require an ECU tune.
