It could also be for ease of removal with an exhaust that runs down the center-line of said sway bar. I have a Perrin exhaust and getting the rear sway bar “hooks” around the mounting brackets can be a real PITA sometimes. You get one hook on and the other hook just barely can’t fit around it’s bracket. You try to the raise both hooks at the same time but the exhaust gets in the way forcing you to only raise one side of the bar at a time.
Center GRMN exhaust: |

I don't think it's center exhaust related either, the GR model has center exhaust but standard bar.
Definetely I'd not say it's obstruction related. |

Are you sure that isn't a pic of a front sway bar used by accident?

The two curves in the middle of the long straight part of the yellow OEM bar gives increased torsional rigidity compared with a same diameter straight bar.
Besides the GR one was introduced before the >MY17 thicker OEM bar so probably it's designed and produced by Toyota, not Subaru. By the way the exhaust manifold of the GRMN car compared with the upgraded CS-R3 race car manifold (afaik produced by Rogue Motorsport quite similar with ACE350) is quite different design: https://racing.tgr-europe.com/wp-con...ge_2017_02.pdf (page 6) GRMN: |

If it is to suit the rally car it may well be designed to allow greater suspension articulation.

Anyway, I don't know why the bends are more pronounced on one vs the other except if they wanted to give greater clearance to something either for heat dissipation or physical interference issues. Maybe one is easier to manufacture? Maybe they were actually less concerned with something like ground clearance or something on the GR vs the TRD. |

That is, as you say, different articulation

Another thing to point out is that a few ideas that were tested in the GRMN car have passed to the new GR86 car. Sad thing is that they couldn't pass the revised FA20 engine with the output of 219 PS (19 PS more) at 7,300 rpm and 217 Nm (12 Nm more) at 5,200 rpm. Problem was that Subaru couldn't make such a well balanced engine and they didn't want to revise their engine production process. So for Subaru the easier route was just to increase the engine displacement, although the rest of the world was downsizing their engines. |

Looks like a front bar to me. People upload the wrong picture to the part sites all the time.
Edit: actually the bends don't match up at all, I doubt that bar is even for an 86. Critical mount points aren't changed willy nilly on production cars. |
