2013 Mustang GT with stock and then GT500 mufflers

First you can hear the stock 2013 Mustang GT mufflers at idle and drive-bys and then the GT500 mufflers. The GT500 mufflers here are brand new and will get louder after 500-600 miles as the packing ages. Too bad but it was windy when I shot the GT500 sounds so that diluted the sound somewhat. But you should hear that the GT500s are louder than stock but not as loud as Roush.
