The Diamond Eye aluminum exhaust adapter adapts a 4.00 inch OD inlet to a 5.00 inch ID outlet in lightweight aluminum construction. The adapter is specified by its dimensions to allow a step between differing exhaust tube sizes where an aluminum transition is preferred. Use this adapter when matching a 4" OD section to a 5" ID component and when corrosion-resistant, lighter-weight aluminum is acceptable.
