Could my cat be clogged?
did it sound any different?
yeah those magnaflow direct replacement sux the p420 always go off on my malibu. if u want to keep a cat i suggest removing whatever crappy cat they put on there and buy yourself a tru high flow one weld it on there. I had no problem at all with my tru magnflow high flow cat that was welded to my downpipe on my monte.

My cat on my zzp downpipe is going bad. I have a replacement in my trunk, but I can't find an exhaust shop that will weld the stainless cat to the stainless pipe 
They are all afraid to do it, I guess their welders suck.
But my car was running stupid rich for a while so I'm sure that was the problem.
