chambered mufflers post turbo are a no no. Also, can yo explain why tuning would be harder?

The "after cat" wide band my not be as accurate as a pre-cat wide band, but sense the wide band is affected by pressure it can't be before the turbo, so it must go after the cats.....or no cats.

BTW here is a video of my exhaust,

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.
