I have done both. And all I can find is the yeti AS3 XC and the Yeti AS3 all mountain. And this frame is different than both. I even messaged yeti cycles and they couldn't find it.
You must be using a different internet than me and Yeti must be yanking your chain. The damper mounting plates came in different styles, which you can see in all the google images, and maybe red isn't so common but that is an AS3. The same in yellow and blue is on this very website. Probably the most unloved Yeti there is, according to what i can see. Probably just fine with better components over oem.
