Stabilizing headers to the engine?

Those of us that have run RB fender exit know all about this.

The thing is, SB headers "naturally hang" pretty much where they belong, that is, there's not a bunch of twisting force on them, so I don't think it's much of an issue. But it certainly won't HURT. Probably just tying the collectors together with a simple brace would be easy, if you can keep from affecting ground clearance.
