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.
- 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.
- Surfaced flanges for a leak free seal.
- 304 Stainless steel construction.
- 100% built in house and made in the USA.
