I had fouled plugs for while due to cracked heads. Anyone ever seen this condition cause the cats to clog ?

I am wondering if my precats clogged ?
 
poor maintainence always has the potential to cause other problems (like plugged cats).

what makes you think they are clogged?
 
i bought my truck with a bad cat from a MAF that was DRRRIIITTYYY!
 
sometimes I think people lose scope of the intention of this board and that is help one another - not be critical
