If melting rubber is a concern...which it sounds like it is. could apply some exhaust wrap on pipe before putting the rubber boot on. it will be a little ghetto but at least the rubber will be insulated from high heat.

Reference my post above creating a dry joint...just need a sleeve for exhaust

otherwise the only other option is to weld on flanges and put a v band clamp on it. That would be a lot of modification.

I agree "best" but yes maybe more welding/moding than i want to get into. If wrapping that joint/gap with exhaust wrap will keep that rubber hose from melting right at that water free joint, that might be a good, however ghetto, way to go for the time being.

At some point, possibly next season, I'll be getting new headers. I would like to put a set if thunder and lightning headers on it. My only reservation then would be if I can get those to fit my current tails. I wouldn't have a problem getting new tails as well, but they would have to he 5" as are the holes in my transom currently. Filling and re drilling new holes is beyond what I want to get into and comfortable doing.

looks like rubber doesn’t melt as long as the surfaces local to the rubber are wetted. I didn’t think he would have an issue with that setup.

I think the welding up holes, adding bungs/jumper hoses, exhaust wrap on inner pipe (after fixing fitment) is your only choice with the parts you have now. You'll know soon enough if it won't work. I'd contemplate running it first time sans engine hatch to keep an eye and nose on the connection. Not sure if the high temp silicon (blue) hose would be better in this application.

i would dump into the jacket. Dumping that close to the header smells like more reversion issues
