    Turn it off!!!
    I read about something that can slide inside your exhaust pipe, Not sure what it is or how it works. I have heard of these before.

    Shove steel wool down the pipe. And I mean the thick commercial grade.

    What Sho-Tyme said. They will fit under the truck. Florida loves writing tickets for straight pipes these days.
