Flowmasters are notorious for droning at certain rpms (usually ~2k rpm). In fact, every car that I've heard with Flowmaster did drone badly. However, when they weren't droning, they sounded great! I haven't been in a Magnum with Flowmasters, so I can't comment on that, but my guess is that they do drone. Any owners out there care to comment on that?
I chose to have Magnaflows welded in and don't regret that decision.
