LOL. I did. I broke three off. Front and rear drivers side, rear passenger side. I put the brackets on with the bolt the pushed down the on the manifold. They were on there for 3 years. Never got around
to fixing them because they worked so well.
Funny story not about the GMT 800, but my old 1989 GMC 1 ton 454 TBI/Turbo 400/4.10...you get the idea.
Towing into Ennis, Montana there is a HUGE long hill. Now I had pulled my exhaust manifolds, put new ones on, new gaskets all new fasteners so no leaks. So that was all good.
Anyway I hit this hill in the middle of summer and for some time had my foot on the floor going 12 to 25 mph...
When I got into town I had to get gas and popped the hood to check everything out. The manifolds were still cherry red.. I have to imagine climbing that hill they were almost molten. LOL.
My one buddy calls me "Mechanically insensitive" He is not wrong, but I can fix most of the stuff I break.
I'm reminded of when the Ecoboost came out. Supposedly Ford put the chassis and drivetrain onto a dyno, ran it at WOT for a week, alternating between peak HP and TQ rpm points. I can't find the picture (Jalopnik?) but I think even the exhaust tips had changed color.
