Down pipe ?

[Amyers]

Does anyone have the bigger 4 in down pipe ? And can you see any difference compared to stock?

honestly researched this for a while. considering that the 6.7 already comes with a stock 3.5" downpipe everything that I have read shows barely if any power gains at all.. you may notice a slight lower egts depending on how you drive. also don't know if your considering doing this yourself but it is a knucklebuster for sure

Thanks bud if it doesn't make that big of a difference I won't do it.. And no I was gonna have a shop put it on..

I will be purchasing one from SDP for my 6.7l. I have the same downpipe on my 6.4l and I made a noticeable difference.

So for a 100 degree drop in egts is it worth it?

i would say so, anything u can do to flow more to keep temps down is worth it, and it flows alotttt more, bends arent as tight, fits perfect

I don't see any other way unless you drop the cross member

theres the answer lol.

no cutting required the stock DP will come out believe it or not oke: also remember the stock DP is a double wall resonator as well like the 6.4's

theres gotta be some more details on this thing....is it really that easy to get to? how come there are no videos of the DP installed?

nah te 6.4 is easy to cut out, and easy to access, so if the access is the same and not cutting required, shouldnt be a big deal.

Do you undo the v band from the bottom of the truck? You can't even see the stock turbo in the 6.7 let alone get the clamp off. You must have to work from the bottom up?
