A throttle body spacer might help some, but there isn't much to do. Re-gearing will help on the highways. I like Flowmaster.

Whatever muffler you can get cheap. A muffler will not give you more power. I put a 16" glasspack on mine and regret it. I would rather have it more quiet, but to each his/her own

Thrush glass pack and only will cost twenty bucks. Only down fall is it's not off set like the traditional mufflers so you'll have to Jimmy here in there. With a cat it won't be that loud at all will sound good. No cat and there obnoxious haha.
