Hello forum members, I don't know if this is the correct forum to post race kart engine parts WTB,but will try anyway;I am looking for either a custom built/cast/fabbed header pipe that looks similar to the attached photo uploaded with this post. Ideally,I need a cast,or fabbed flange with the specific dimensions:center-to-center header mtg flange bolt spacing should be 2.75 inches,and header flange exhaust port dimensions should be approximately 2 inches Wide X 1 inch Tall! The uploaded picture is of a 135 cc Vortev(??) 2 cycle kart engine header pipe with a CTC of 2.5 inches(which could be adapted to my engine if all other specs are close enough to work on my MB project engine!!
