I am putting on a new Two Brothers C-2 carbon muffler on my '99 600 F4. The Two Brothers muffler that was on the bike was rashed, sent in for repairs, where Two Brothers trashed it out. Any rate, studying the mounting instructions, I am pretty sure I understand it all except, where the "S" pipe meets the header. Am I to use a muffer gasket there? Or use the High Temp. sealant that came with the muffler. There is no mention of either in the instructions, except, that I use these sealant, where the "S" pipe joins the muffler. Any help out there? Or wait till after the weekend and call Two Brothers.

muffler gasket should be replaced.

Thanks Triax, I did call Two Brothers and they said that it only needed the clamp. I did put some of the Permatex High Temp. sealant in there along with the joint between the muffler and pipe as well.
