Anybody have any idea which ones pair up nicely? I'm looking for an exhaust system that's not so loud but not so quiet either. And if anybody is aware of a tuner that can hold multiple tunes without having to have a laptop in the cab? But if not, a good tuner that will improve mpg's and performance. I'm really inexperienced as far as aftermarket performance parts, and the Ram in general, so any definitive help or advice will be GREATLY appreciated. Thanks.
