Couldn't you actually take off a total of 16 points if the exhaust is wrong and not good workmanship, cleanliness, and rusty? Glad to see it in the rules along with mandatory 1 point for plastic heater plenum. I think the Assistant head judge is working towards doing a very good job. Now if the judges will be consistent and take off the points. Now the judges will have be able to show the owners it is in the rules.
