meford4u: I have some experience with lots of different setup, and from what I know about you. I would say, you wanna run a long tube header, an oversize flex pipe, then find yourself a Hermoff highfolw cat for a 5.9 liter or so that has matching ID's to your exaust tubing. if you have a 2.5 exaust, order a hermoff highflow cat for a 5.9 liter with 2.5 tubing. then, you go and cut after the flange after the flex pipe, like 2 to 3 inch after, then you remove as much tubing as the cat is long, then you weld the cat right in the exaust line.

from this setup, you will benefit from an underbody cat and since you have a supercharger, the cat will still work wonder and get warm realy quick.

you might wanna also on the side run colder plugs and mild cams and cam gears.

maybe in winter a a port and polish kit, I know I will... B)
