Needs new Exhaust Gaskets?

[Canuck]

Hey everyone,

I've got a good feeling i might be losing some much needed compression due to a leak in the exhaust port.

when i fire up "the beast" after a cleaning i noticed the steam got hot enough to show me where the leak was..I would turn the throttle and could visibly see the steam being thrusted away from the hole. It was coming from the pipe going to the engine ojn the left hand side if sitting on the bike (right if looking from the front)

could even a small amount of escaping pressure cause idle problems or anything??
