[QUOTE="Strokersace, post: 1504220, member: 622"] I know it sounds crazy, but on our two 6.4s, I removed the 4” mufflered systems in favor of a 5" with the same Donaldson muffler Mike is using because that setup is MUCH quieter and no drone! On the one truck, the 4" flopro with muffler was bearable but still too loud. The other truck was a 4" flopro straight pipe. The drone was horrible with this setup. Both trucks have a 4" 2 piece down pipe and the 5" on back with the big Donaldson muffler. Quiet, no drone, but still sounds aggressive when you want it to. I've contemplated adding a resonator to get it whisper quiet, but haven't felt the need to yet. Both trucks are cclb's. [/QUOTE]
