Re: exhaust tubing

I measure the GM #3931829 and 3931830 at 0.089" at the front end (the slotted end I pictured in my post above) and 0.102" at the rear end.
I measure the GM #334932 front pipe at 0.076" at the rear end. I can't get a reliable measurement at the forward (manifold) end because of the flare. The easily measured part is simply an extension which is permanently attached to the pipe.
I took some photos of the rear end of the rear pipes and the outlet end of the forward pipes. These appear like they MIGHT be double walled at these ends. If so, though, the inner pipe is very thin.
