If looking for budget, buy a Flowmaster 80 or Magnaflow muffler, pick out the tips you want, take to local exhaust shop. <$300 I put my Flowmaster on and am happy with it. For couple hundred more you can have them build a catback dual with x-pipe. With a little research, and getting the parts yourself, you can have a great sounding, custom exhaust for less than an aftermarket CBE.
