down pipe

[soyer]

im new to diesels and im goin to run stack but a want to run a stright 4" from the turbo back, dose anyone no were i can get a one?

well you can get a 4 inch downpipe from a lot of places. Then you could just go and get enough 4 inch pipe to go back to where you split for the stacks. Beans Diesel Performance sells 4 in downpipe pretty sure

everything on the net says a 4in down pipe isnt worth it just get a 3and 1/2

yes sir they do, thank alot... with a stok truck will i see any improvement with just 4" stright pipe with 5" stacks?

If I had to do it again I would have gotten a 3.5" over my 4". Too many fitment issues. Not sure about performance difference, but can't be that much until you get ALOT of ehaust flowing.

exactly! its not worth the trouble. 3.5" is more the sufficient!
