Stubborn Exhaust Gaskets
 

I've had to remove the exhaust on my 2001 Africa Twin and I'm having trouble
removing the header pipe gaskets - can anyone please advise on the best way of getting them out. I've tried levering them with a small flat bladed screwdriver but don't want to put too much pressure on
them for fear of slipping and damaging the castings. They're tight as hell.
