i dont really see the dip stick touching to be a big deal really. its not gonna bounce on it. if you like i pushed my fingers between em, then gave the pipe a little bend and it was right next to it.

i set my lower band clamp up so its bolts were top side turned and lifted away from the fire wall tunnel area, its got like a inch or so of free room, its never hit, or my brake lines would be trashed by now, cause thats whats next to it. you can reach down from the pass rear of the engine to the clamp this way. extension's help of course.

i put my cross over on first, then the front header to the cross over but with it pointed up, then turned it down to the head. worked for me 2 times now.
