Once I removed the forward controls I mounted the bottom pipe (forward cylinder) and marked where the BUB pipe begins it’s bent up. The I cut the stock pipes small cross pipe and filled the hole. Marked exactly where I would need to join the two in order to keep the length the same as the upper pipe and welded the two together. Once that was done I mounted everything up. The lower mount bracket was too far in to I gave her some heat and bent it up to give me an extra 1/2 inch to clear everything
