Hi there. I have the dreaded exhaust leak from my manifold due to broken manifold studs. I haven't been able to get the nuts off the driver's side down pipe from the manifold. The nuts are completely rounded. I have tried the 'nut removers', to no avail. I currently do not have access to cutting torches however that may have to be the route I go. Any suggestions would be appreciated. Thanks
