Anyone remove the rear resonator that's past the muffler? I come from a diesel background as a farmer and my first truck was a 06 6.0L. All before the DPF and all that stuff. Exhausts were fairly simple to me.

Have had my 2020 with the 6.2L now for a couple years and wanted to do an axle dump exhaust similar to my old 6.0L. It was tucked up way underneath so you couldn't see it and i liked the clean look. Well to my surprise when I crawled under to look and there's quite a few more things going on under there than I expected. Looks like there are 2 resonators as well as 2 mufflers?? Well where i wanted to cut there's that resonator that dumps past the rear axle. Do they need 2? I don't really want to change the sound of my truck as I enjoy having conversations with my wife and kids without having to yell like my old 6.0L lol. However 2 seems overkill and havent seen that before now looking at other gas trucks. I don't towing often but would hate to have to deal with a bad drone after removing it. Has anyone else removed it? Or even do all these trucks have that? In my research seems like not all do? Would appreciate any help. My truck is a CCSB if that makes any difference to having the 2nd resonator or not.

 

? pics from under there?
