Killer B Motorsport 321 Stainless Holy Header Max VE with Up-Pipe – Subaru STi, WRX, Forester XT, Outback XT, Legacy GT

This equal length header is made from thick-walled 321 stainless steel, which is alloyed with titanium for strength at high exhaust temperatures. The Max VE version uses a stepped, large-diameter 2.5-inch secondary for higher exhaust flow. The collector is a cast 347 stainless high-velocity merge, and the primaries are short, symmetrical, and mandrel bent.

An up-pipe is included. Each header is inspected, assembled, and pressure tested before it ships. It works with OEM EJ25 oil pans and the Killer B Motorsport oil pan. It is made in the USA.
