Good one, don't forget the nickel based anti seize if there is aluminium involved. Also let us know how it goes.

2 stud Heli-coil fix on extended exhaust to Exhaust manifold is successful. However appears there is a 3rd stripped stud. I did a soap test spray. I see foam on top right nut and stud. I know buy experience this nut is not torking like the Heli-coil fix on the other 2 studs. Attached is photo of the foam soap test on 3rd stud and nut. 2nd attachment is videio my new exhaust mixer working good.

you can buy the kit and coils cheap on Ebay I just did the same thing
