Had to make a new pipe to clear my t-case cross member. Used old junk on the existing flanges and added a flex pipe leftover from a Celica so it can take a hit. Now it snakes through without rubbing on anything. Back flange still hangs below the frame. I can't seem to get it up in there with the set of exhaust bits I have on hand right now. I may address that later if it snags on things. I did add a bung for the AFR gauge O2 sensor.
