Andy,
	On your photo there appears to be some exhaust leakage around the pipe closest 
to camera - white around the entry point.
	The cat will introduce extra heat, and the mounting arrangement may be 
introducing mechanical stress at the elevated temp - have you seen the internal 
construction - is there a baffle connecting the end of the input or output pipe 
to the casing in the area where the split occurs? if so that would suggest 
flexing at elevated temperature - metal softened, more movement...etc
	Have you thought of using a flexible coupling between the CAT and muffler, 
perhaps in conjunction with a stainless steel muffler .... just a thought.

Regards
Bill
