Not sure if the correct term, but the “H pipe” connecting from the headers to the exhaust tips is leaking on my 1991 ST1100. Anyone know the best source for a replacement and some tips for changing it?

If it is rusting away then Delkevic makes a compatible Header/Collector unit, you can use the STock mufflers.
I did mine and it was easier than I expected.

This part that's integral to the left exhaust header?
Yes, I think you’re right! I hadn’t looked at too closely initially...I thought the headers dumped into a separate collector and then to the tips.
If you look at any of the parts fiches, the left side is one continuous part, as shown by ST11Nut's image above. I wasn't aware of this until this thread.
I have an oem and an aftermarket one that I'm not using PM me.Not sure if the correct term, but the “H pipe” connecting from the headers to the exhaust tips is leaking on my 1991 ST1100. Anyone know the best source for a replacement and some tips for changing it?
