ETS Maxflow V2 Equal Length Header V-Band Subaru 2004-2021 STI / 2008-2014 WRX

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 flows into a huge 2.5" secondary for maximum scavenging and exhaust 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.
- 3-bolt up pipe flange options.
- Stock replacement design.
- Low profile design for maximum clearance.
- Surfaced flanges for a leak-free seal.
- 304 Stainless steel construction.
