Thanks Evan and Countryboy for your suggestions and experience with possible heating around the exhaust stacks. Evan, I have suspected that the noise factor with this muffler would be pretty high since it is virtually devoid of baffling. No matter, I love the noise! Especially while in flight. I am hoping to finish priming this weekend and then get to color base coats within the next two weeks following. I will have to put in panel lines and rivets first, and that definately takes time. By the way David, thanks for sending a larger picture of your Spit. It is Beautiful. Isn't that an Indian Theater trim scheme? I may be wronge. Either way, it is gorgeous. Hope mine turns out as nice.
