Nitto RG's are on stock 20x9 rims. No lift beyond stock AT4 setup. Only had minor rub in front of drivers side and only in reverse at full lock. Zip tied the bracket behind the liner to the fender mounts and rub is gone. No cutting needed in my case. I only purchased the passenger side SwingCase so don't recall there being any distinction. Maybe drivers side would be a problem because of assist handle.
Love it. It really depends on individual taste but I think it’s about perfect and I get many compliments on it and people asking “what exhaust is that? It sounds so sweet!” It’s actually louder than I expected on cold start but then quiets down quickly and I have virtually no drone. Generally quiet cruising unless climbing a steady grade, then I’ll sometimes hear it.
If anyone has one of these they haven’t installed, I’d really like to see the installation instructions and pics of all the connectors on the wiring harness including the wiring colors going into them if visible. I’d like to see if I can maybe fabricate my own for use with my grill lights. TIA

I believe I'm starting to see this on my 2019 AT4 as well. I initially though "rock chip" but there doesn't seem to be any scrapes or marks. I'm going to watch it closely and follow up with the dealer if it continues/expands.
I could see the lights flash in the reflections off the vehicle in front of me at stop lights.
Just so you know, I had initially wired my grill lights from that fuse as well but noticed they “flashed” when the auto-stop cycled and didn’t like that so moved to the side marker light fuse. Just and FYI.
IMO, without a lift and other trimming, I don't see how 12.50's would work. Maybe if you tied back other areas could be OK but I don't know what clearance to the control arm would be. It's hard to get a feel for clearances under full compression. I have/had very minor rub, only in the front on the drivers side when backing at full lock right. That said the clearances are very tight. I zip-tied the liner bracket pulling it towards the bumper last night and I believe the rub is gone. I'm going to look at clearances closer this weekend and may zip-tie back other areas just to have more room. It also depends of course on the wheels, use of spacers, etc. I went with stock wheels and 11.50's because I didn't want to get into much in the way of mods and I don't really want to lift it.
@Erod_66 I'm certainly no expert but to me, I think it would make it worse. Seems to me like it's equivalent to adding width and moving the outer radius of the tire farther from the axis of rotation when turned to lock. That, in addition to encroaching on the upper control arm, is why I think 12.50's require so much more trimming to get them fit.

About the same as oem tires.
Popedecoys. Where is yours rubbing? Just curious. I have found a minor rub, on my drivers side only at full lock to the right backing up. I haven’t had any rub going forward but I know it’s very close. Trying to decide whether to install the 1” motofab spacers I purchased. I went with 11.50’s and stock rims in trying to avoid any rubbing and agree, no way anything wider, or with more poke would fit on my vehicle without rubbing.
Installed 35x11.5x20 Nitto Ridge Grapplers using factory wheels on my 2019 AT4. Suspension is stock and so far, appears to be no rub. Very tight fit though, 12.5’s would definitely rub.
Scheduled to have the same 35x11.5 tires installed. Where is the rub/point of contract?
The rub must be coming from the width as my AT4 stock tires are 275/60R20 which are 33" tall as well but clearly narrower. I've talked to some that say Ridge Grabber 35x11.5 fit without rub but that 35x12.5 will require trimming. All assuming stock 20" AT4 wheels. Hard to know what to believe.
Installed Borla type S on my 6.2L AT4 about a month or so ago and would agree with everything TylerAt4 says. Cold start is louder than I expected but settles down fast and sounds glorious after that. I do have a bit of the “helicopter” sound when DFM kicks in but it’s not bad IMO. Much less noticeable than i expected.
Installed the S-type (#140733 stock tips) about a week and a half ago and agree that it’s louder than I really wanted on cold start but seems to settle down quickly and isn’t bad on the highway or around town. I haven’t noticed the deceleration issue with my AT4 which is a 6.2L 10-speed. I may switch to the touring if possible. Going to give it another week to decide.
