With the exhaust, it depends on your personal preference. The downpipe is smaller than any filter back exhaust you can get. For the intake, I like the S&B, the AFE is also a good setup. Let us know if we can help.

will i notice and sound difference from the 4" to the 5". i have heard that it will be deeper and i have heard no there is no difference until u delete the DPF

and will the intake have any effect on the sound or tone of the exhaust ?

I went with the MBRP 5" dpf back and noticed maybe a little deeper tone, but not much. I've also heard of some trucks throwing a CEL with the exhaust, but my truck never through any.
