Grimmspeed Equal Length Exhaust Header 2015-2021 WRX

This is GrimmSpeed's Equal Length Header and has been designed to provide the turbocharger with an uninterrupted flow of exhaust gases to greatly improve the spool response while increasing the horsepower, the torque, all while saving weight. The equal-length layout will produce an aggressive, race-inspired exhaust tone throughout the entire RPM range and makes for an excellent bolt-on modification. This header will work with the factory turbocharger or factory-like aftermarket turbochargers.
