Exhaust rear header splitted up

I will try, thx..

And what about the Y-pipe connection? I have a slip-on Akra, and it blows out some exhaust fumes and grime there, not much but the engine can still running if I "plug in" the Akras with my hands

Yeah the graphite gasket needs replacing fairly often have one in my garage ready for a change:



It is meant to have the 4 slits up the sides, I cants see anything else wrong with your pics apart from the missing clamp? do you have the clamp?

Akras dont have a gasket like the above, the clamp holds it tight, you do get a bit of black residue coming suppose thats normal on the akras.

I've never changed the graphite ring, and the bike has ~20k km now
I read that it can worn fast but I didn't ordered one yet..

The part number is on the box above its not expensive.

Think you have to undo the exhaust to get it off though

The old ring just disintergrates over time.
