5". Wish I'd gotten 5" instead of 4". Now I'm married, poor, and you know the rest. No more mods for me.

You will see zero performance benefit with a 5 over a 4. You will probably see some clearance issues with a 5 that a 4 won't have and no matter what anyone tells you a 3.5" downpipe is perfectly fine. 4" downpipes are just an unnecessary pain in the ass.

Re: 4" or 5" exhaust whats your take?

I love my 5 in straight pipe, but you can not mount your spare under the truck anymore. Its sounds really crazy when you put your foot in it. I do a lot of HWY driving and it does not bother me at all. I had a 4in with a muffler and I have not noticed much more road noise at HWY speeds. I got whole exhaust for $350 shipped from farm boys diesel.
