I know of no other way to remove this exhaust nut, and it does a perfect job.
Used on 1974 BMW R60/6.
1/2" drive, on end of tool slightly larger than 1/2" drive adapter. (Somewhat distorted)
Works well for my application.
The nut wrench was a dream! Perfect fit and easy to get enough leverage to get those tricky exhaust nuts off! 10/10!
