My catalytic converters violating Title II of the Clean Air Act

My products have been detected as violating Title II of the Clean Air Act. However, catalytic converters can be sold normally on Amazon. You can see that many sellers are selling such products.

I have reviewed the relevant regulations of the Clean Air Act. Catalytic converters do not belong to the products that are intended to defeat, bypass or shut down emission control devices, and they are allowed to be sold normally on Amazon. Moreover, we have the EPA certification. I sent an email to contact the Amazon platform. They asked me to provide the CARB EO number of the products. But it is stated in the product description that the products are prohibited from being sold in California, our products will not be sold in California.

They also asked me to provide more product photos. I did as required, but it didn't work. I feel like I'm chatting with a robot by email. The relevant team doesn't seem to check the information I provided. I don't know what else I can do.

I hope that the Amazon sales support team can help me solve this problem.
