Technical exhaust temperature

[Mar4ix]

Hi, punto mk1 , 1.2 8v., exhaust joint after catalytic converter (two bolts). it is leaking there, i have a new seal there , but it still sipping through. Can i put hi temp gasket/silicon. It says up to 315 degrees Celsius, may use for exhaust manifold. Would that silicone/sealer would be fine for that joint .

Thanks

i use granvill
so long as its after the cat and second lambda where fitted it wont cause silicone failure to the lambdas
