my neighbour has a 6.0L superduty. He has mufflers on it, with dual pipes (maybe dual mufflers too) but its the best sounding truck Ive ever heard.
I know this doesnt help, but I thought Id stick it in. lol

I just took my muffler and tailpipe off since Im planning on some exhuast work tomorow, wanted to hear what it sounded like without a muffler....and HOLY CRAP!! does the turbo ever whiste now! I know the 6.0Ls have a real whistly turbo with a stock exhaust, so I imagine it would be really loud after muffler removal...my exhuast is polite untill about 2200rpm, starts getting a little noisy at 1800rpm under load. This is on a 96 7.3L

keeping in mind I just pulled the tailpipe off, there are no turn outs or turn downs on it yet, and the exhaust exits directly under my rear seats...it is suprisingly quiet, that statement is relative to the large engine size, pipe size and the fact that there is no cat or muffler. Of course the truck is loud, but my brothers truck with a 351w and dual 3" flow 40s is just as loud. Except my trucks a little quieter under 1800rpm.

heres a vid of my truck. revving to ~3000rpm with no cat, no muffler, stock downpipe (flat 1"x3" pos on the first gen PSDs). Pipe is 3" at the flange to the DP for 2 inches, tapers up to 3.5" straight back to a 45 degree bend and kicks out before the left rear tire.
