I have exhaust leaks in my ball joints that need attention. I have searched the site and the answers are limited. Lapping the joints was suggested but I am looking for any other suggestions. I tried 'muffler mender' but the leak is small so the putty just flaked out. ANother idea is the putty and then doing a muffler wrap like used on racers but it would look tacky in my opinion. I guess it will be under the cowl and not visible but I will still know it is there. Ideas?
