Hanging 911SC OEM exhaust issue

[rcautox]

I picked up a new to me 1980 911SC fulfilling a 30+ year dream! The exhaust is just hanging off the cat with the straps not connected to anything. The car was raced ages ago but exhaust system sure looks factory to me. Looks like my cat is separating from the exhaust trying to support the weight (photos 2 & 4).

My exhaust straps hold a mount with two central holes (1st photo) Is this correct?
Did PO just fail to reinstall the exhaust mounts?
Does an exhaust hanger mount to the holes in the 3rd photo?
Is the cat also missing support (photo 5)?

Thanks!

There is 2 8mm holes just below the oval in motor mount.
Hanger attaches there. The 2straps holding muffler attach to the support
The cat is supported by the muffler and the heat box and crossover pipe
Looks like you need another cat, or muffler, I have several of either. PM works best.
The biggest problem is the 6 bolts at the front of the cat, usually rusted and need to be burned off.

Think red arrow pointing to one of the 2 bolts you’re referring to?

If those are the hanger bolts it feels like I’m missing a bracket which would mount with those bolts and the bracket on my exhaust then connects to that missing bracket with the two holes blue arrows are pointing to?

Already time to find a shop manual!

I think the holes in question are circled in green, these are use to attach the mount that holds the muffler straps. Your red arrow points to a bolt that holds the assembly to the motor.

Thanks Mike, the photo is just what I needed. My exhaust is hanging so low I didn’t consider the mounting holes are (I assume) accessed from the engine compartment above!
