Yeah straight-piped exhaust is for 18 year olds. I can’t even imagine it at this point
I straight piped the stock 3" in my '99 5.9 Cummins and it was insanely loud... this 6.7 with 5" wasn't terrible in normal driving situations, it was loud but not obnoxious at all times. Under boost and towing it was quite loud, but you might be surprised how it sounded most of the time.
Watch the video I posted with it straight piped... it wasn't stupid loud.
