OK ladies and gents I need some help on picking the right exhaust. I bought a 2012 Dodge Ram 1500 w/ 5.7 hemi. This is my first dodge that I have ever owned and now its time to put my own touch on it. I want to start with the exhaust and after hours of research I now need advice. I'm stuck between Magnaflow, Flowmaster 50Hd, and Aero Turbine 3030. I want the loud growl and roar when I get on it. thank you for any help.
