7mm bolts are very uncommon here in Europe, too, therefore I would really be amazed if you could find good tools to repair such a thread in the states. But who really needs that ? tap it with an 8mm thread and it is fine, more reliable and the parts are available at any Volkswagen garage. Especially for exhaust studs I would take care. Aluminum head, SS repair thread and a zink plated stud. Then there's lots of heat and moisture. And of course some kind of copper grease. ... Go for M8 and skip the problems with M7.
