I have the FI resonated high flow cats and it's my only concern with the design as there's no support bracket. I've found at least two documented cases, on this site, of the FI high flow cats cracking at the weld. Both were in the same place. I check mine every time I change the oil.
I've gone so far as to order another OEM cat brace and plan on installing it with custom-made and welded on brackets to the FI pipes. There was a noticeable increase in vibration at idle after installing them. The vibration disappears just off idle.
