If your wanting more sound, go atleast a 50 series, and even then it wasnt much different.(i had a 50 on my 05 silverado 5.3)
If you want something that sounds and flows good without being too loud, id go 18" magnaflow.
Youll need 3"in and 2.5 dual out
A 50 Series is pretty loud on a newer Ram. I had one on my old 4.7 and that thing roared; especially around 2000 rpm. There's a sound clip linked in my signature below if you want to hear it.
