Like Omer said....  the high-temp copper (colored) silicone works 
wonders on problematic exhaust mating surfaces.  Use it with a gasket; 
or two gaskets if the alignment is poor.  Squishable gaskets help 
compensate for flanges out of square, etc.  Cat' converter heat might be 
a little much for it but it still helps.  Also, be sure to use metal 
gaskets on the cat' not cardboardy ones.
