If I’m designing icons/images in native iPhone 5 resolution, what @x multiple do I need to export them at for iPhone 6+? Just use @2x? That’s too big right? Example: an icon is 44px x 44px. If I export at @2x it’s 88px. That’s too large for 6+ right? What’s the right multiple or ratio from 5 to 6+.
In the past, from non-retina to retina the ratio was just doubled. So an icon of 22px would be 44px. Very annoying for Apple to do this… :/
Thank you!

Ricardo is correct in his answer of @3x, but I'll take a shot at answering your question as well.
If you're working from Retina resolution assets already, the upscale factor would be an additional 1.5x for the iPhone 6 Plus.
For example, your 88px by 88px Retina icon would have to be up-scaled to a resolution one and a half times that amount for the iPhone Six Plus: 88*1.5=132 .
