I just bought a 2001 Chevrolet Silverado 2500HD 4x4 and I don't know what kind of exhaust to put on it. I want something that isn't too loud, more of a low rumble but sounds mean when I stomp on it. Any suggestions would be appreciated.

 

If I were you I would Go with Flowmaster they have the deep rumble sound to them unlike the magnaflow and others. If you go to flowmastermufflers.com and go under features you can hear sound clips of each series. For the 2500hd i would go with a50 series.
