This flange is used in our VR6 Test Pipes & High-Flow Cats. It is CNC machined from 3/8" thick 1018 cold roll steel and is drilled for through-bolt connections. The center hole is machined to accept 2.5" piping. We are offering this flange separately for those who want to build a custom exhaust system and connect to the stock Mk3 VR6 downpipe. Gaskets are available separately.
