3 Bolt Collector Flange – 3.5″


Includes one pair of exhaust 3 bolt collector flanges for use with 3.5” (3 1/2”)tubing.  This flange matches a standard 3 bolt collector gasket (not included).  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 and a surface ready to weld to.

    Another great product from these guys. I have bought items several times and have never had any issues. Always a great fit. Keep up the good work.

    This was my third or fourth order for header equipment from Andy. All of my orders reflect the top notch quality that I have come to expect, the fit is right on and ready to tig weld. Andy has also been very helpful with advice and always willing to help. As I collect more oddball engines, I will continue to obtain equipment and advice from Andy’s firm.
