Default won't see any real improvement with a high flow cat unless the one you have now is plugged. I'd check the cat to make sure it isn't melted and plugged up inside.

As far as the muffler, if you can't tell what kind you have, no telling whether it's flowing well or not.

I put on a single in/dual out Magaflow and a Volant intake on my '99 5.2L and it helped with throttle response, mileage and it sounded a LOT better.
