What's the difference between a stock cummins and one with stacks. the sacks are a whole hell of a lot cooler, and f'ning loud. So
I've never had any tip determine what my exhaust note is. I've always had it be determined whether it had an X-pipe and that muffler or h-pipe and that muffler. 3" pipe here or 3.5" there all thw way to 5".
Stacks are so loud because there is no muffler or resonator. You can get the same effect without them. All you're doing is running the exhaust out the bed instead of the back.
I've been threw so many exhaust tips on my current trucks and not a one did a damn thing, except be shiny at the end.
