I have a feeling that I might end up eating my Fulsac Headpipe. The Jackpot 2/1/2 was recommended to me. I still have my stock D shaped head pipe cross over that goes under the frame; and I see that the Jackpot cross over is another $120.00. Is the Jackpot cross over flow that much better than the stock to justify the extra $120.00 over the stock D shaped pipe?
