Absolutely none with the valves closed. Sounds like my wife's tahoe.
Valves open you can hear it some at highway speed (70-80 mph), but it isn't what I would call drone. Less than my gen V camaro had with long tubes and corsa catback. Can still hold a conversation, talk on bluetooth, listen to podcasts, etc. I run valves open 95% of the time (really just close them in my neighborhood, if i see LEO...) NPP is actually kind of amazing.

I just bought TSP 2" headers in January and had to ding three header tubes on the drivers side (two for the steering shaft, one on the bottom for the motor mount)

I took my Mbrp pipes to a shop and had then expand the splayed end so I could slide the cat pipes into the Mbrp pipes. I figured this would reduce chances of leaking. I also had the shop weld up the splayed end of the cat pipes also.
