For all of your information, my optimizing process goes beyond the typical job people do. I remove more material from the Y section and re-build the transition for a smooth transition and better flow. If I ever get a chance I'd love to have my Y flow tested against an MSDS or other after market, as i think i can flow nearly as well if not better for less money.
sorry to keep this going, but i did PM you, i never heard back
