Looking for advice.  I have a small leak at #3 rotor housing to exhaust flange, detected by a bit of discoloring on a SS baffle that is about an inch away.  I installed with the stock Mazda flange gaskets.  I have re-torqued the nuts, no change

 

Should I: a) Remove and replace gasket?

               b) Remove and coat gasket with high temp RTV?

               c) Throw away all three gaskets and use only high temp RTV?

               d)  None of the above and ignore the leak?

 

Thanks,
