Ditto on what they said about the type S. I love mine and don't regret it at all. The cold starts are aggressive but quickly quiets down. I dont notice any drone at speeds but I do listen to podcast the entire time.
I just installed the S type this morning on my 2020 AT4 6.2. I did it all in my garage without jacking it. I only needed to cut the factory exhaust right behind the muffler. The new system went in very easily.
Overall. Super easy job and only took 2 hours with no assistance. I love the sound and am very happy I got the truck without the factory performance exhaust and just purchased it myself.
