I ordered an axle-back type S late last week in black stainless and it came in yesterday evening. I installed it this morning, it took about 1 hour in the driveway, using me, myself, and I as the install team. I went the easy way and simply removed the support brackets instead of fighting to pull the rubber ends off and having to wrestle with them on the install. Four 13mm bolts which were easy-peasy to remove and reinstall.
I waffled for days whether to grab the touring model or the type S as I really wanted the dual pipes as opposed to increasing the noise. Thus far, i am happy with the sound--it replicates the sound my AMG twin turbo GLC43 Coupe had with its exhaust. It starts with a rumble, but then quietens down. Now to drive it and see how it sounds on the open road!
What I was not impressed with was how much Jeep "crushes" the OEM pipe instead of mandrel bending it, I tried to capture that in this photo, but it does not do it any justice:
