I wanted something that would make power, so I went with Magnaflows. Even with an offroad x pipe and dumps, my car is still quieter than most mustangs I've heard. If you want to make noise, go with the Mac or Flowmasters. If you want to make power, go with the Magnaflows or a set of Dynomax Ultraflows.
