pop

So the cost of having someone weld me a torque pipe is prohibitive, but someone suggested that I make one using pop rivets, cold forming with a hammer and anvil, and high temperature sealant. Anyone tried this before? Anyone think it would be a waste of time and fail horribly?

I was just riding along earlier today and I noticed the engine wasn't really putting out a lot of power when I turned up the throttle and all of the sudden POP! I look down and the spark plug is dangling from the connector and I have to pedal home. This is really weird as the threads don't...
