ETS V2 MAXFLOW HEADER- SUBARU STI
The wait is over! Extreme Turbo Systems is proud to release our new Subaru STI V2 MaxFlow Exhaust Header for the 2004+ Subaru STI.
"We designed our ETS V2 MaxFlow Header to be a direct factory replacement header. We start off with large 1 7/8 primary runners that come together in a true low angle 4-1 merge collector that then flow into a huge 2.5" secondary for maximum scavenging and exhaust flow."
