Unfortunately, those prices are fairly accurate. Because of the key component (platinum) inside the cat, replacement parts are very very expensive.

The cat is fairly toxic too. I'd be very careful handling this. Also, depending your region, your entire exhaust system might be rusted together. Jacking up the car and removing the cat via ratchet set might be impossible. You'll need a torch.


You can look for a "race" cat. It's a replacement and should include the O2 inlet, or dongle. These run about $300, but still might trigger that CEL (Check Engine Light) and might not be CARB (California Air Resources Board) exempt.


Do you currently have a CEL on? If so, reset it ... but I need to know your model / year / trim / engine type of your Accord.
