Exhaust cover removal problem

Being lazy, I took my SS to a local reputable dealer to have new tyres fitted.

Not a Duke franchise so I gave the mechanic the handbook info for removing the cans before you can get the wheel off etc.

Unfortunately, even using Snap On tools, he has managed to strip the Torx screw head on the inside of the cover, so its now stuck in place. We tried several different ways to free it and failed.

He now wants to tig weld a nipple onto the end of the screw to get some purchase on the screw to turn it. This seems reasonable (you can't get a drill in the restricted position and the screw is stainless, so will be difficult to drill out anyway) but can anyone see a reason not to attempt this?

Good question. If he screws it up, seems like replacement covers will be in order...replaced by him, of course.

I did the same thing to one of mine. I used a dremel and a cutting wheel to cut a line in it so I could get a flathead socket on it and get it off. Almost stripped that too, but managed to do it. The one place you'd think Ducati wouldn't used fasteners made out of parmesan cheese is the exhaust.

Have not tried that, but great idea, where it’ll fit!

For real. Had to use the welder myself. Replacing those screws which face the tire with a larger head type after changing the tire.

Well, it all worked out fine, except the female thread is damaged. Looks like it was a manufacturing defect. Annoying, but solvable.
