This weekend we started on the exhaust. Luckily the gods were with us and after several hours of very very careful and delicate work we were able to get the complete exhaust out of the plane without breaking any studs.
My old exhaust we found is very thin and some of the ends were a little chewed up. The good news is that I have a whole other exhaust ready to put on the plane. We opted not to tackle that this weekend but the plan is as soon as we have another free day we will put the 'new' exhaust on the plane and get her going.
