The support off the diff is the most important one. I use an old fashioned rubber strap/hanger, bolted to the diff, and a 90degree bracket at the other end which is in turn clamped with a U bracket/clamp to the pipe. 

Because it's not standard I don't think I can clamp it there. The pipe passes directly under the diff centerline with only a few mm clearance. The silencer is held solidly though and doesn't move at all. 

Think I need to look at the entire system and make a plan.
