Just grabbed a Magnaflow catback (dual muffler) from another forum member and put it on a couple of weeks ago.

There 'is' some drone around the 1700-2300 RPM range, but outside of that there's none at all. When cruising on the freeway I'm above that range, which works for me.

To each his own though.
