The T6 to 3.5'' billet transition flange has been designed to improve the flow transition for a 3.5'' round tube to the traditional T6 turbo exhaust housing. Our flange is machined from 1018 cold rolled mild steel to resist warping under extreme temperature conditions. All HSP CNC machined components have a true position fit that exceeds anything you will find on the market.
