I've just got installed new flex exhaust pipe. After driving for few minutes, when the engine started to get to operating temperature I started to notice a plastic odor inside of a car. I started to be a bit scared, but managed to arrive home. When I opened the hood I realized very strong burned plastic smell. I examined the surroundings of the flex pipe and didn't notice it was touching anything.
Today I've called the car repair shop, then visited them again and they said it's a normal smell for newly installed flex pipe. We looked together from below and the pipe doesn't touch any other pipes or elements indeed. The smell is however pretty much terrible and it's necessary to close vents and even windows to avoid it.
I also got changed a muffler. Some additional twist is they said it's very hard to get one (muffler) exactly to my specific version of Hyundai i30 and they installed the one from Kia Ceed (which is kind of twin car).
Does anybody know if this smell is indeed normal?
