Exhaust flange
This exhaust flange is drilled and tapped with an 1/8″ pipe-threaded hole to facilitate installation of a pressure gauge to be used to check exhaust back pressure. The flange is shipped with a stainless steel pipe plug installed in the hole until such time as a pressure check may be required. The flange also includes a gasket and mounting bolts. While there were never any official torque values for the exhaust flange, we recommend 20 ft. lbs.
