7" round mufflers

[Bullitt-]

  Planning my exhaust and want to keep the cans in the rear but don't care to pay for the OE style replacement muffler. I have studied what's available in the 7" diameter & it seems there are only a couple of reasonable options. What are your experiences? I would prefer something not tooooo  loud but that fits reasonably.
Thanks

I've used the round magnaflow cans before on a Challenger with a nicely built 360.  Sounded great and fit nearly perfectly.
