3 or 4 inch dual,exhaust for 6.0

[Whitetrash06350]

Does anyone have any experience with this? I hear people putting up 5" single but what about duals? Any advice?

All depends on what you want. It's basically a preference thing. Most go single just cause it's cheaper. 4" vs 5" won't gain any performance but 5" will be a little deeper sound. Go with what ya like and what fits ur budget. I wish I would have done a 5" single but got 4" single cuz it was cheaper.

Duals look cool, but I'm soooo glad I went with the 5 inch. I love it!

Plus I think it comes stock with 3" or 3.5" so 4" min. I have 5" and would not trade it for 4" because of the deep growl I get.

I just installed a 5" diamond eye single turbo back exhaust with cat delete and its FRICKEN AWESOME!!!! I am glad I went with the 5"

stock down pipe is like 3-3.2" and the rest is 3.5" on back. check some online diesel shops for deals, alot of them are running at least free shipping. i bought 4" turbo back no cat, no muffler ss 409, 6" tip, free t-shirt and free hat for 330 bux with free 2 day shipping.

the 4'' dual kits give about the same exhaust note as the 5'' single. the pipe is either 3.5'' or 4'' from the turbo to the tranny crossmember. I would recommend a helping hand if doing a dual kit. They are a pain to get lined up and looking right.
