I'm in the process of replacing my
exhaust riser and to do so will be installing a reducing coupling between it and my muffler. It's a different story as to why I need the coupling, but my question has to do with what sealant/caulking is typically used on
exhaust systems?
For anyone interested in the longer story of why and how I am replacing the riser on my Gulf 32, and why a reducing coupling is needed, see my blog at

That I have been able to disassemble the old stuff makes me think it isn't 5200, but does that mean people use 4200? Or is it polysulfide? All these connections occur after water injection, and so do not reach very high temperatures. I figure one of you out there has an informed opinion...
Opinions?
Thanks
