Hey y'all! I'm thinking about changing the exhaust on my Silverado (regular cab, short wide bed, 4.8L V8) once again. It currently has straights on it and before that it had a Flowmaster 40 series. I love having straights on it, but they've developed a terrible rattle from all of the vibration that seems to be non-fixable. Does anyone have any suggestions of what system I should try next that will still be loud enough to rattle windows? Thanks!
