The engine size plays a huge role in how loud the exhaust is. There is a pretty big difference between the 6.0 and a 5.3.

Here is a light takeoff in mine- this is with 4 cats and a resonator pre turbo. I also have my wideband in my tailpipe, and it only reads about .1 leaner than when up front.
light throttle takeoff in turbocharged AWD 5.0 Explorer not getting into boost.
