Hey folks I have a 2002 zx3 with 61k on it and counting. I took it to the shop on the count of rattling upon startup and idling in multiple places and was told the welding is rusted and causing the noise. Trouble is the parts for the resonator muffler etc were estimated upwards of $600 when I also find things on the web for half. I was told there are special parts for this model. Is this true? If not can someone recommend repair options or websites for parts. It would be greatly appreciated. If it is this much is this a type of repair that can be done in multiple visits as its my way to get to work. Thank you all ahead of time and I'm sorry if I don't understand enough.
