3 pieces by manufacturer or by failure?

By failure, the one piece bracket was broken into 3 pieces.

When I first bought the van I would get a rattle in idle after the engine reached a certain temp and traced it to this bracket. I removed the half connected to the DPF to eliminate the rattle. I drove it like that for several thousand miles figuring it was much better than the two parts rattling. I still think the separated brackets rattling are more troublesome for the flex pipes than no bracket at all. Only after reading here did I find the additional info. and since the replacement bracket was cheap and modified I replaced it last summer. It was a strait forward replacement though not easy. I expected to have alignment issues and just placed each bolt before tightening in a wheel lug type of sequence, but it all tightened down without any apparent opposing forces.

When examining mine, my first thought is that the problem is the bracket is acting as a heat sink between the exhaust and transmission mount. One side of the break is a completely different color than the other side of the break.
Thank you for sharing. I would be reluctant to operate without the support of a bracket because the exhaust system is heavy and unsupported, especially over rough roads, may over-stress other components, particularly, the flex pipes, turbo.

Sure, but my only point is, if someone has a full failure and there is going to be some time before replacement, if it's going to be unsupported anyway, that rattling is surely going to make things worse. I probably did over 15k miles without it. And I don't know how many miles before I got it the bracket was broken.

And I'm not 100% convinced that it's not the whole system wanting to move as a whole that's causing broken flex pipes and bracket failures when you have a rigid spot. I seem to remember several other exhaust mounts in the system all designed to flex.

Interesting had the New DPF 4 bolt bracket replaced at 60k scheduled B maintenance for $0.00 2014 I4 2500

An excellent point! And, all the more reason the "hard" brackets, prone to failure, should be modified to flex as well?

Excellent! I argue it should be covered under the emission component warranty.
