Whats the difference between just having flowmaster mufflers or the whole catback system? Am I missing out on power? will the catback system complete my exhaust setup of BBK shortys and BBk 0/r h-pipe. And will I feel the difference? My flowmaster mufflers have been on my car since I bought it 6 years ago, do they go bad or clog or anything? They still sound good.
cat back system or just mufflers?

a full catback will be a little more power and a little louder due to the larger diameter pipes...
When I went from my factory catback with welded in flowmasters to 2.5" flowmasters with turndowns I "think" I felt a difference. Obviously it was louder due to the turndowns...
It is up to you if it is worth it or not.

With a catback you also get larger diameter (2-1/2") mandrel-bent tailpipes, but I don't think the pipes will make any difference on a mildish 5.0. The stock tailpipes measure 2-1/4" and really aren't bad at all. The biggest restrictions in the 5.0 exhaust system are the stock headers, cats, and mufflers; not the pipes that communicate between them.
The biggest reason for selecting a catback rather than just mufflers is if your tailpipes are rusting away.
