Don,

Thanks for your measurements. Going back tomorrow to Weatherfield. Have a CC 3 disc insert with packing. No center restrictor. Sounds more muffled but my home measurements were still a little high I think...very windy day throws it off. They measured behind the car though I think the state statue is supposed to be perpendicular but not less than 70 degrees. Is that right? Since they measured from 50 ft behind the car were they in the wrong? I made a restrictor like the fellow showed in the picture but used perforated Al and expanded metal. Seems to have lowered it further. Will be testing again later if the wind dies down. Check with your knowledge about how the test should be done with regards to angle of measure and let me know.
