why doesmy car run sluggish now?

[SLow_POke]

ok i busted it (the cat) all up inside cause i can hear it all rattling now but none of the stuff will come out??? and it still feels exactly the same. could it still be the cat even though its all busted up now and how can i get that shit out of the cat now LOL? and thanks for your help so far guys

do u have a STRIAGHT THRU MUFFLER. if not ur getting ti stuck on there.

yeah its a straight through muffler but its just sitting in there (the cat housing) rattling no matter how much i revit. oh yeah and somebody said to me that my car might be in "Limp Mode" maybe becuase my O2 sensor migh be out. ???

if it was in limp mode u wouldnt be able to rev pass a certain RPM.

the only thing i can add is maybe take off the cat and gut it that way, the honey comb design might be broken but in big pieces thats why i wont blow out,?
