CAT question

Okay guys/girls!!! I replaced my CAT a month ago because my stock one was gone. It was setting off an engine code and I was getting that weird smell in the cabin. I went to a muffler place and he was able to get an aftermarket one on there. Now a month later the engine code is back which means I need another CAT. Any ideas? Is it because I went aftermarket? Do you think something could be leaking internally??
 


Most aftermarket cats will still throw codes.It dosnet mean anything is wrong just the pcm reading the o2 sensors report.Your cat is flowing too good thats all.Is it magnaflow?
 
i had a magnaflow cat and my ses light stayed on about a month then finally deleted code and never came back.
 




I just had my emission test done, dont need it for another 2 years! Im going to give it three more weeks, then clear the code. If it comes back on I will bring it back to where I got it put on
