I've been thinking about replacing my muffler as well, but just hadn't gotten around to saving up $250 for a Calmini one... but may go the Flowmaster/Borla route now. The thing I don't want is an IN YOUR FACE stinkin LOUD muffler. I'm looking for a nice low rumble to let people know that yes, this is a truck, not a car. What kind of sound does yours have? And I too would like to know how much the installation and the whole bit cost.
Thanks
