4 inch or 5 inch?

[mega1]

Should I go with the 4in downpipe and dpf delete or should I go 5in all the way? I have an 08 and the only other mods I plan on are an edge and maybe a cold air intake. Any info would be great.

4" is plenty..even with a moderately moded truck.

That is all opinion really. I have seen threads back and forth about the 4 or 5 and my .02, do what makes you happy or more important the pocket book if ya know what I mean.

5" = lower EGTs and quieter

If you look a few pages back you'll probably see a few threads about it.

I have the 4" and i am happy with it. I never see really high EGTs and it sounds fine. I imagine that the 5" has a different sound (throatier) but according to my pocket book the 4" is sufficient.

4inch is plenty and with the right muffler plenty quiet. I'd say the 5inch is more for looks than anything unless you pushing tons of power..
