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.

Features

1 7/8" primary runners with 2 1/2" secondary for maximum flow.
CNC mandrel bent runners.
Custom .100 USA made thick wall tubing for durability.
Low angle 4-1 merge collector for maximum flow and exhaust scavenging.
Slip fit connection for ease of removal and installation.
2-bolt or Vband up pipe flange options.
Stock replacement design.
Low profile design for maximum clearance.
