Dupree split downpipes - same as you. I bet the cooling of your intercoolers between runs with your system gave you a pretty big boost even if you couldn't run with it on. My run was pretty heatsoaked when I got 495 RWHP but at 23 degrees timing. The diff is you did your run on stock timing. That totally rocks.
