The wait is over! Extreme Turbo Systems is proud to introduce the new ETS V2 MaxFlow Exhaust Header for the 2004+ Subaru STI.
Designed as a direct replacement for the factory exhaust manifold, the ETS V2 MaxFlow Header delivers exceptional flow without sacrificing fitment or ground clearance. Large 1-7/8-inch primary runners feed into a true low-angle 4-to-1 merge collector before transitioning into a massive 2.5-inch secondary—maximizing exhaust velocity, scavenging, and overall flow.
