It will require you sending the section of exhaust to us to cut the flare off, install the new nut, and weld the flare back on. Secondly, if the gasket (donut) has chewed away at the exhaust port, we rebu ild the exhaust ports of cylinders. Danny is still chunkin away at tool kits, but we have several exhaust nut pin wrenches available. (as well as our new Propeller hub but tool ).
