Exhaust sealant

My slip joints leak on my expansion pipe (TSR Evo).

Is there a flexible sealant that can be used on slip joints in these challenging locations?

Hi Martin, hope all is well in the sunny south. Is this what you are after. I remember these type of slip joint rubbers were doing the rounds when I had a TSR Evo. This link is an example, I think I got mine from JB Tuning

I've been using 100% silicon sealant on my exhaust joints for years, as have a number of friends. It's flexible, cheap and widely available. If it's good enough for professional MX racers, it's good enough for obsolete Italian shopping bikes :D

Hi Nick.
I am trying to seal at the header end of the pipe, but thanks for the link. M
