4" exhaust a must?

I already have the stock 3 1/2" stainless system. Can I get enough flow by just doing a muffler delete? Not turning her into a dragster or anything. Am planning on installing a wildman chip and I already have K&N CAI installed. Any suggestions backed by scientific data or personal use are greatly appreciated! Thanks!

The stock exhaust on any of these trucks are just fine if thats all your lookin at doing. A straight through system would help the truck out and let her breath but its not a must. I was truely suprised how quiet my truck is after putiing a 5" straight turbo back system on. Id like to say I could feel a diffrence in the truck but not reeley.

Nothing scientific here but IMHO no if you aren't going to substantially increase fuel flow then no you don't "need" a 4" exhaust. Personally I am planning on an in/out 3.5" muffler (like the walker muffler) and calling it a day.

3 1/2 should be fine. Delete the muffler and enjoy the sound. Mine had a 4" turbo back and I deleted the muffler. Love it.

Ditch the K&N, dont filter good enough for turbos. I have 4in Straight turbo back. Sounds pretty good IMO

You will be fine with the stock pipe and deleting the muffler and CAT. 4in really doesnt increase the flow much in comparison any thing bigger then that is just for pure sound unless you are pushing high horsepower
