951 winter progress

Mike a couple of P car noob questions…

What’s the torque tube you’re reffering too? I’ve never even heard of that part, probably due to my permanent residence in FWD land…

And why do you have a cross over tube / what is it’s function? I stared at the pic for quite some time… kinda coming up blank on how the exhaust system works on that motor.

Hoping perhaps I’m not the only one wondering so maybe those answers will help someone else…

Either way, good luck as usual.
