I am having trouble removing the exhaust from the C70. It has been
sitting for many years and is in pretty rough shape, rust, etc. Still trying to get her going again for fun.
After removing the collet plate holding the exhaust pipe to the head, I am unable to withdraw the pipe. I suspect rust and corrosion is the problem. Tried a few wacks with a rubber mallet but no luck. I am concerned about damaging the head.
