if you want to replace the entire exhaust system go with a high flow cat if not not just get a cheap one from the parts store i run the magna flow cats on my f150 and have had no problems with them they have been on for close to five years now

magnaflow get's my vote and can be had at summit as either a direct bolt on or universal mount for a good price. I'd get a high flow if it was me even if you don't replace he muffler and tail pipe.
