Have a SupremeIII that I just got up and going runs really smooth. Tops out at about 35 with holes drilled in baffle. I have a dellorto 14/12 and a 15/15 that I can use on it, and am not woried about fabrication intake. My question is what is the best pipe I can get for the stock cylinder porting and either carb? I realize I will have to weld up a pipe to existing header or creat new header from scratch. Thanks for any advice.
