Do you know what killed your cats in the first place? I assume it has been fixed?

If so I would say go for free flow cats or high flow cats, they will complement the rest of your exhaust system.

most likely an H2o slash a year or so ago, thats about all i can figure, my mechanic told me hes surprised it lasted this long i have 65000 miles on the truck and its still the stocker, ya he kinda laughed when he said that because dodges are supposedly supposed to have Crappy cats??

I have heard they have crummy cats too, don't know how much merit there is to that, I intend on replacing my cats when I roll over 50,000 miles and can replace them Smog legally before they fail.
