It's the air injection system, which at one time was connected to the air pump. It appears to have been cut off and sealed at some point. Removal involves some dismantling of the exhaust system, something you may not want to do as hardware can break and you'll then be in a world of trouble. You can cut it into smaller pieces and avoid that hassle, but you still have to remove the air injector nozzles and seal the openings in the exhaust ports or seal the outer end of said air injector nozzles. There is risk involved here, too. I'd just leave it where it is until it's time for major engine work. BTW, your sump plate is 90 degrees out of position. The drain plug should be on the left (driver's) side of the engine.

It is a 1978 911sc row. The pipe/tube is broken. Can I drive it like this without causing any damage?

Since it is not functional, I would remove it. Even if it were functional I would remove it. The spider is composed of two parts: the curved black pipe you see which was formerly attached to the air pump in the engine compartment and six nozzles which are screwed into the exhaust ports. Methodically soak the fittings with penetrating oil such as PB Blaster or Kroil. Heat gently with a torch and soak some more. I did this probably ten times over several weeks before removing the assembly. After this preparation the assembly will likely be easily removed. There are horror stories about breaking the fittings inside the cylinder head. Go carefully. The holes in the exhaust ports can be plugged with these:

Thanks Targalid,
I think that will be my long term plan, I'm heading out this weekend for a short trip so I think my welding job will suffice until I can remove it and plug the holes |
