Thanks for the reply EndlessAzure. I posted the picture again. Yeah, I found it strange that the diagram don’t show it. I brought the car brand new from the Toyota dealer and it came like that already. I’ll take picture of it tomorrow under the car with the two locks that is still on. Like you said, the hangers don’t seem like it would fall off by itself, but with those lock I guess it keep the exhaust from moving around. This is on a 2015 frs. Don’t know if they start adding it on those models and up.
