Suggestion #1 use the search button
Suggestion #2 you're going to have to determine what exactly it is you want done. If you want a quality exhaust system done the right way, it's going to cost you some money. Flowmaster and Dynomax mufflers seem to be the favorites around here.
You also need to determine for yourself whether you plan on just replacing the rear muffler or redoing the entire exhaust system. Again, this will cost money.
But if you just want a 3.3L that sounds loud and obnoxious without spending much money, go buy a hacksaw for 5 bucks and start cutting pipes apart.... :p
