A couple of weeks ago I was stopped in Indiana In my truck. Well I wasn't really stopped I had just pulled into a McDonalds and got out of my truck and he pulled up. He said that my muffler was to loud. I have dual Flowmaster 40's he didn't give me a ticket just a warning. My question is Why can motorcycles be as loud as they are but cars have to be quite? It makes no sense to me.
