I've been thinking about getting a muffler for my truck, it is currently straight piped. I am thinking about getting a flowmaster 4 inch 2 chamber race muffler. I know it's not a diesel specific muffler but whats it gonna hurt. Just wondering what some of y'all think about this. I think it would sound badass!
