Stock dp is 3 inch. Yes you will hear the difference and your engine will thank you for the lower egt.

Yes, the stock downpipe on the 6.0 is 3.5" and you won't have any noticeable difference by upgrading to the 4" downpipe other than a bunch of dents in your firewall from having to beat the new downpipe in place...

That's no chit! Everytime my truck articulates a bit, that engine sounds like its sitting in my glovebox because the DP is hitting the firewall

Articulation in a Super Duty?? You make me laugh, sir.

BTW, I didn't notice much (if any) difference when I upgraded my downpipe from the stock (3.5") to the aftermarket downpipe (3.5"). If I had to do it all over again, I might have just gone with the cat-back system.

It twists, a little . It doesn't take much to make that DP kiss the firewall

Not enough to write home about..
And I have a 4" DP, I'll admit it gave me problems but once I got it in just the right spot it has yet to do rub. This has been 2.5yrs now

You don't have any hills in TX to test that out on though, Ben . I should fix mine, because all that weight that's on the DP, is directly added to my turbo
