Often, the doughnut gasket between the stub pipe and header on the rear cylinder is the culprit. When the engine is cold you may be able to feel exhaust gases escaping through that junction.
That same gasket is used not only on TLs, but also on SVs and DLs. Therefore, it is surprising that none of the shops in my area keep them on hand. They are always "special order" items. :coocoo Anyway, that's likely the part you need.

Yup, i had the same issue. Those pops can go a long way to making shit of a CF can too!Often, the doughnut gasket between the stub pipe and header on the rear cylinder is the culprit. When the engine is cold you may be able to feel exhaust gases escaping through that junction.

+1 On the header gaskets, also check all the locations that the exhaust joins together, so at the base of each can where they bolt on, in the middle of the system where the two "halves" of the system join together and also have a look right up by the rear cylinder where the exhaust slides over the header stub.
Start the bike up and put your hand near the joins and see if you can feel any gases escaping is the easiest way.
Good Luck!
