Could be holding the heat shield in place?
I will see what I can do, but it is possible that the heat shield is long gone...
I attached another picture.
I found a youtube video that shows the exact same duct clamp at the same location, that makes me think that this can actually be a factory installed part (see attached picture)?
Thank you for your response.VStar650CL wrote: ↑Fri Sep 23, 2022 8:21 amThat's a rusty heat shield being clamped to the pipe. Weird, the parts drawings usually show the shields when present, but I guess it has one there after all. Anyway, that's a repair, it is not OE. Nissan doesn't use that style of band clamp for anything except intake boots.
I understand, but I own this car since its birth, and I don't think a service technician would add a clamp without telling me about that.VStar650CL wrote: ↑Fri Sep 23, 2022 10:04 amEverybody uses band clamps to fix busted tack welds on heat shields, and busted tack welds are almost inevitable on anything more than about 8 years old. There's nothing unusual about that. The wife's '13 Altie has two of them on the flex pipe shields, along with probably 75% of the older Nissans on the road.
If that's what you think, please read this Nissan bulletin and check out what the "fix" is. Mind you, this is recommended by Nissan. Your repair order would read something like, "Performed repair per bulletin NTB14-018," with no mention of a clamp except as a part number (if it was warranty) or a shop expense:
