Does anyone run exhaust stacks? How do you like them, and how loud are they? All I know is that they look sweat. Let me know Im thinking about getting some.

I have dual stacks on my Cummins. My other cummins is about to get a set as well. They sound good, and you always have the option of adding a muffler in the mix as well. We carry the Grand Rock stacks, which is whats on my truck.
