bad muffler???

I just installed a flowmaster muffler, I have come to the conclusion it is bad. It was misfiring and I finally have that squared away(i think) went to autozone had them run diagnostic cleared it then went for a ride and came back and no codes showed up. But I'm still getting that sound out of the muffler of a misfire and around 55-60 mph i get a little hesitation like a misfire. Anybody have any ideas????

Some mufflers cause exhaust restriction is installed backwards. Not sure if FM mufflers fall into that category but you may want to investigate.
