Also, i have run open exhaust at Skope, Amon and at BMW and did so at the recent Ice Breaker, i blew 103DB so had to sign off with the DB guy. I got pinged at Timaru 3 years ago and had to changed my exhaust. I have a slip-on exhaust system i can change in 2 min, my advice to all racing at Denny Hulme next year is to do the same. I can't advise anyone to run open exhaust's but should they do so, have it so you change quickly should you be required(never been asked yet).
When i took my Mustang to Sears Point and Thunderhill a few years back, friday and Saturday where open exhaust days, sunday we all had to run mufflers, most of the historic Trans Am don't have a slip-on muffler system so their race was Sat and they stood down on the sunday. It seemed crazy that one day is OK but the next isn't, BUT thats the "consent rules" they have to work to up there and like i got told, better than NO open exhaust days!!
