Is the Force II, Series 50, drone substantially less pronounced than the American Thunder, Super 40, and is it day to day live able? I have the American Thunder on my 2014 GT and the drone was too much for me. I don't want my neighbors to hate me. Thanks.


  • Hey Ken, So the Force II are going to be noticeably less loud than the American Thunder. Of course I cannot give an exact level but they are designed to be just a slight upgrade from stock. Flow master, in terms quietest to loudest, goes Force II -> American Thunder -> Outlaw. So there will be a decrease in sound so that your neighbors will not hate you.

I don't see a place to input bed size, I have a 5.7 bed. will this system work?


  • This system will work with a short bed or long bed as this comes with extension pipes that you can put on your truck if you need to have them on there.
