Yes i've cut thru the hood on mine, to make the TA hood scoop functional, i had to cut two openings on either side of the middle support brace. In my case i did not cut through it like you would to have a 671 blower stick through the hood, I suppose you could and it shouldn't warp anything if you were careful doing it. I don't think i'd try using a simple jigsaw like i used on mine (drilled 6 holes, then used the saw to cut through each panel in between the holes) there was a little warpage on the long cut on the outside edges, i believe there are two layers of metal and i didn't have the hood clamped down while cutting, and may have slowed down the speed during longer cuts, under the hoodscoop you can't tell but as the picture below shows you'd have to be carefull to avoid a wavy edge. The center part is where the center brace is, you could cut through this, but i'd probably recommend reinforcing the edges to provide support after the cut was made. Not sure if the cut would adversely affect structural integrity.
