Includes one pair of exhaust flange for the Chevrolet V6 4.3L motor (see motor applications below). These flanges are cut with a CNC HD (High Definition) Plasma cutter out of 3/8” Pickled and Oiled (P&O) steel. P&O material is hot rolled steel that has been dipped in acid to remove the mill scale and then a light coated lightly with oil to prevent rusting. The end result is less work to clean off the mill scale as needed with hot rolled mild steel.
4.3L, 262 cu. in (1985-95)
*more applications/years may work, verify before purchasing.
Ports designed to be used with 1 5/8” exhaust tubing.
