I know this thread spans over some time, but I wanted to put in my $.02, for the next person who searches. I had a Magnaflow muffler #12229 (single in, single out, 14") put on, and originally left the resonator on. It sounded good, for the $100 I spent, but I was curious about how much better it might sound without the resonator, and would that add drone at highway speeds? Well, I recently took the plunge and had the resonator cut off (but I kept it, just in case) and a stainless steel tip put in its place. I am beyond thrilled with the low growl that I get in town, coupled with the fact that at highway speeds there is no noticeable drone. Radio off, on the cell phone is the best test for me. I even put it to the test with the windows all open, in town, with my wife in the truck trying to talk to me. Not only were we able to talk, but she LOVED the sound of the truck.
I couldn't be happier with the Magnaflow. I couldn't be happier without the resonator. All for a grand total of $200.
