Well most people on here are going to tell you not to do stacks, but if you can look at them both put them in the bed and see what you think of em

5in is nice but i would def go with the 6in. sounds amazing. i have seen and heard trucks with 12in stacks and they are WAY to big. they look goofy. take in to consideration, that stacks are extremely loud while your in the cab. it gets kind of annoying. i have a full 5in pipe from the turbo back with no muffler and a 6in tip. that sounds real good. not to noisy in the cab, but the person behind you will def. know it aint stock.

I say 6" or even 7". 5" stacks look to small IMO. I used to run 6" miter's and they looked good. They are very VERY loud so I would recommend a resonator and internal mufflers.

Pics are in my profile for a reference.

Just an honest opinion from me to you i think 5's look to small as well. 6's just really fit it seems like. Just and honest opinion!

6in all the way.the bull haulers shouldnt be too loud in your cab. my turnouts arent that bad, but my buddies miters are significantly louder in the truck.
