boost is addicting huh?
how are the ends of your pipes finished? you need a lip or bead to help hold them on there. a cheap solution is a length of wire rolled and trimmed to slide over the pipe end and then braze or solder it in place (much easier to do than welding) if you have a bead roller you can roll a rib on it. even a row of weld beads or spots that sit proud will work (mig welder with wire turned up and voltage down a little)you want it as near the edge as you can get so when you clamp you clamp behind it.
