Perrin Performance Equal Length Header for the Subaru WRX

Subaru WRX STI Equal Length Header from Perrin Performance
Increase both horsepower and torque in your Subaru WRX with the Perrin Performance Equal Length Header! Instantly gain 15-20 wheel horsepower and about 20 pound foot of torque. This part is perfectly safe to install and doesn't require an ECU tune. On a 2015 WRX we have dyno results showing the stock header vs the perrin header, this 2015 WRX also had a 3" turbo-back exhaust and no ECU tune to give a better perspective of the dyno graph. Not only will you get more horsepower and torque gains but you will also notice quicker turbo spool as the Perrin header produces a smooth and balanced exhaust flow thanks to a properly designed collector, allowing the turbo to spool up quicker compared to the stock header. This header could also withstand bigger turbos if you  do plan to upgrade your turbo. Constructed out of 304 brushed stainless steel for both quality and appearance!
