Ets V2 Maxflow Exhaust Header with 2-Bolt Flange for Subaru STI (2004–2021)

Description

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. 
• Confirmed Fitment with XL Oil Pans like IAG and KillerB
• Surfaced flanges for a leak free seal.
