Re-routing plumbing vent stack for sink around new larger window
I'm located in MN, and I currently have a kitchen sink under a 4' window and I want to replace this window with a much wider one. My venting / drain pipe is 2" ABS. From the P-trap the drain runs horizontally about 2' to a T. The top of the T vents straight out to the roof (about 6" from the edge of the window), and the bottom of course connects to the main drain line under the floor. I am going to be installing a window that is about 18" wider on the vent side. This means I need to re-route my vertical vent. My question is, can I make a C shape around the window using 45' elbows, or do I need to just turn it once go over a few feet and cut a new hole in my roof? Please see attached diagram of two separate options I am looking into.
