| i had similar problem with my 1st cag,u have a few options,1*,u could buy a couple of feet of exaust wrap from any exaust repair shop,wrap it round your exaust(u need to wet this stuff 1st,then tie it on with some wire)let the engine idel till the exaust bandage dries,or 2*u could fabricate up a peice of sheet metal,i used galvanised,to cover or go inbetween the exaust and tank,or 3* u could buy a different exaust/tank to suit,or u could do both step 1 and 2(bandage/sheet metal light gauge will do fine).
when this happened to me,i wraped an old welding glove around the pipe,not a good idea,when i stopped after some hot laps,i thought my balls were on fire as the smoke was bellowing out everywhere,the glove died a fiery melting death.
