muffler choices

OK, here's the deal. I just bought a 68 Dart with a well built 360. It is loud as hell. Shakes the neighborhood. My neighborhood is a quiet one and the local police are tough.I'm looking for a muffler that will give me a nice rumble, but not wake the dead. LOL!! The 360 has hooker headers and I'm planning on running a 2.5" exhaust through an X pipe. Any suggestions would be greatly appreciated.
Thanks,
Frank
