Which one is louder?
 

Between Cummins, Powerstroke, and Duramax, which is the loudest and which is the quietest "stock" in years 2004, 2006, and 2008?

i would have to say cummins is louder stock or tuned up... and i am not sure but i would think that the duramax is the quietest

I would think so too, but we have a 2005 powerstroke and too me its pretty loud, stock. And i've heard some stock cummins on youtube that sound very quiet.

yea but were the ones you heard the 08s bc my mom has an 08 and it sounds like a kitty cat:moto::lol88:
the 04 cummins are prolly the loudest because they dont have as much epa stuff... but ive heard a few loud power strokes

any power stroke I ever heard is wicked loud. as far as engine noise. The newest I heard was an 06 and the engine noise is much louder than my 04. when the 3rd gens came out they tok themselves out of the loud engine contest and left it to the powerstokes

Yea, the loudest by far is going to be the powerstroke. It's all in the injection event. The 6.0L does not feature common rail injection, which means they can't have a pilot injection to quiet the engine down like the duramax and cummins of that year span.

Watch this video and fast forward to 2:30. Its a 2007 with a 5.9L.

oh.. idk but my bro has an 03 with out the muffler and its the loudest pickup ive ever heard i can hear him shift into sixth a couple miles out of town... and if you pass some one in mine or his 03 and ur running bout 2400 rpms when your tail pipe hits there door you can make someone :edit: their britches its so :edit: Loud

Then watch my video of the 05 Powerstroke.

my 95 dodge is loud as hell with 1 7 in stack. no thats has nothing to do with what ya'll are talking bout though. but the 2004 dodge man. tranny is louder then the auto.
