Just had GT500 mufflers put on my car today by the local Ford dealer. 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.

Does anyone know for a fact that these are "packed" and if so, is it stainless steel mesh or fiberglass?
