What would cause the B pipe and the exhaust manifold to break at the same time? Is it something that slowly gets worse over time, like a little crack that just expands? Can you drive over something and damage it since it is under the car? Does one part breaking cause the other to break?
Back story- I’m still trying to get to the bottom of how our car went in to the dealership for an oil change and new tires and leave with those things broken (though they won’t accept responsibility and could well be blameless). Took it to the dealer and they noted the car was loud when they completed the work but not before they started the work. It was so incredibly loud that there is no way we wouldn’t have heard it so we feel 99% confident that things were ok before the oil change and tires. I have always had great service from the dealership. We used to take it to an independent shop but they were neglecting things and we eventually made the choice to go to the dealer. I have always trusted the dealership and this Honda dealership is quite well regarded from many I have talked to. Do I think they sat back there and poked holes in the exhaust system? Of course not. But, I don’t know how else all was well at the beginning and not at the end. Seeking a general understanding of how these components get damaged since my husband neglected to ask when he was there.
