on my 21SP i have Johnson pipes and cans and they are sprung where they attatch to the barrels, where the pipe slots into the bit that is bolted to the barrel it seems to blow a bit as i get a good bit of smoke when i fire it up. this seems to stop after a while but i was wondering is there a type of gasket or sealant i should use.....

cheers
