The T4 to dual 2'' billet transition flange has been designed to improve the flow transition from 2'' round tubes to the traditional divided T4 turbo exhaust housing. Our flange is machined from 1018 mild steel to resist warping under extreme temperature conditions. All HSP CNC machined components have a true position fit that exceeds anything else on the market.
