Replacement cats

How finicky are these GMs with aftermarket cats? I want to pass emmissions in my state of Pa. I have SLP long tube headers with the cats gutted out. I want to replace the system with new Catalytic converters. What do you recommend? The vehicle is a daily driver so it have more than 5000 miles a year so emissions will not get exempt.

Kooks Green cats have the best reputation. I have a set, but haven't put them on yet, so I can't give you a more personal opinion of them.
