4in or 5in exhaust?

Sound wise is there a big difference between the two? I'm not building the truck for big power so other than sound I can't see any other reason to go to a 5in.

5" has a deeper, what I call a v8 sound.

On a 6.4 I'd do the 5". That's what I had on mine. Loved it.

Another vote for 5". Personally, 5" sounds best on all V8 diesels.

Well then that's the route I'm going to go. Thanks guys.

Five is louder than four, no real power difference unless you got over 650 or so at the wheels.
