6" will be more satisfying to look at.

I have 6" stacks, and find they have a deeper tone idling, and sound like a harley at WOT....they snap real hard. When I tried 5" they were quieter and higher toned at idle, and at WOT had more of a raspy sound....sounded like 4" straight pipe but closer too the cab, and had a drone at 2000 rpm...the 6" stacks dont have the drone. BTW i have no muffler or cat either....so adding either of these will obviously change the sound.

i was thinking about 4" stacks. i'm not a big fan of big stacks...i think they look too gaudy (don't know if i spelled that right). but if ya'll are thinking the 5" are too small i may rethink it. i plan to paint them black as well. does anyone have any pics of their rig w/ 5" stacks? i'm also looking for tips as well.

where is the best place to get a "kit"? for those that have had their stacks on for some time, do ya'll notice the welds on the bed (where the stacks bolt to the top of the bed) starting to crack? a buddy of mine has told me about this. at least that it has happened on fords.

Mine are Grand Rocks that I bought through Black Cloud Diesel. I now have mine secured to the bed pretty well and took off the brackets to the sides of the bed. The L-brackets will break in time although Grand Rock has a new design now, I believe to help prevent this. Nothing on the bed is cracking either.
