Maybe a little, but not nearly as much as most people think. The variable geometry turbo kills a lot of the deep rumble exhaust sound that you hear in the 5.9. so unless you change that, which even I don't recommend, you will always run much quieter. Plus the 6.7 has 2 pre injection events, 2 main injection events and one final event so it really quiets things down. Sorry.
