I just ran new exaust on my 300TD and used simple rubber mounted hangers.
I tack welded the hangers on the car and a round metal rod to the pipe. The round metal rod slides in the rubber mount.
It's just exaust and not rocket science, just as long as the pipe is not mounted solid and is on some type rubber hanger where as you have some give all will be well.
The only way I could see me having problems is if the motor mount s broke and the engine
Had a lot more wiggle than usual, and even I think mine would still be fine.
I will take photos of my hangers if I get a chance tonight.
