Ok. Yes the pipes are a slip fit. There is some leakage as there is a black sooty film on the pipes near the junction. Odds are that is where the fumes are coming from.

I'm surprised to see that there is nothing in the design to tighten the pipe diameters to each other. There are two bolts that are designed to keep the side pipes from slipping off of the header pipes.

Certainly welding a flange plate on each piece would be the ultimate solution, but then the ceramic coating will need redone to keep it corrosion resistant. That seems like a winter prodject to me. So what is the best idea on a temporary quick and dirty fix, to get by until winter?
