Anyone have a link to factory black exhaust tips?
Also interested to see white paint matched flares..

You have to modify your tailgate to work with the multi pro and the LED badges. (Relocate badge a tad and cut hole for wiring) You can probably search it on the forum ( I find the search feature not to bad if not as common a search as “tires” or “exhaust”).

And the guy posted what was all necessary I just can’t recall where it was but I believe it was titled “ Led or backlit badge/emblems”.. He has a decent walk-through with pics of what he all had to do..

googling gmc.com or .ca or . Wherever your local, and hit model and then accessories will bring up the badge/ emblem options and a good selection of other goodies

I'd like to see some white paint matched flares too.

I've also added Oracle Colorshift DRL's to my list of mods as I wanted amber DRL's. Not sure I'd recommend this mod cost/benefit wise. Difficult mod as you have to remove the headlights and "bake" them open to install. They are not as bright as I would have liked and you have to be careful ordering the corresponding controller to be sure the controller has persistent memory.

I just purchased a 2021 AT4. I love everything about it so far. Except I find the headlights (specifically the high beams) very lacking in brightness. Has any one changed out the LEDs to HIDs. Trying to figure out if it would be worth it or not? Haven’t been able to find much in the way of help online so far.
