if you just want the sound, pretty much any old universal muffler with a ddecent sized tip will suffice. No point spending money on something you don't want. Any Ractive, or APC, or wutever muffler thats hi-flow, with a niceely sized tip will give you that F&F sound you desire. You can get thos cheap. Or, Axel back exhaust will work well, giving you a slight gain in power aswell. Cat, same, but more power., headers back. Really good sound, and very good performance, especially when matched with an Intake, best option Cold Air Intake. Prices range from 20 for just muffler, to 600 for CAI and Full exhaust
