Here is my cowl after the cut, I made a template to overlay and cut out.
Also FYI, I had my lower cowl off for awhile while I was messing with stuff, not really advised. The upper cowl then serves as basically a heat funnel to the intake, here is my intake temp after setting at a stop light in 70 degree ambient.
Another point, I spent a few hours today mocking up a divider to try to keep the intake noise down by keeping it away from the cabin vent. I got a pretty good fit and it reduced the cabin noise little to none, I might still print out a final version because I like how well it holds the intake pipe so it doesn't move around in the cowl so much anymore.
