Npp vs non npp mufflers

Hey i own a c7 and just installed catless headers and an x pipe routed to the stock non npp mufflers. Was wondering how much of a difference in sound it would be to just put on a 200 dollar pair of used npp mufflers off facebook instead of paying 1000 for new name brand mufflers. Dont care about the valves working just sound.

Seems pretty normal to me. I already have the headers and x pipe but missing the gaskets. Wondering what everyone else thought.
