Desoto Hemi 276-345 Exhaust Flange


Includes one pair of exhaust flanges for the Desoto Hemi 276, 291, 330, 341, 345 hot rod 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 lightly coated with oil.  The end result is less work to clean off the mill scale as needed with hot rolled mild steel.

    Had a minor problem, but HG was quick to step up and make amends. Would recommend HG to others. The flange was cut on a plasma cutter. The cuts are very smooth, but do taper.
