Well had to wait till weekend as i am on stupid shifts..
rang Blueflame up and they where exellent sent me some new Baffles this morning...
tried the warm the exhaust trick up but it REALLY WAS STUCK IN...
so out came the drill

pliers and everything... but... success its out admittingly not going to be able to use it again but wft...
the guy at Blueflame says if your going to keep it in then apply some silicone lub around the edges to prevent it happening again..
just glad its out...
