2006 HHR LT 2.2L - Manual - Cat Converter ?
I’m looking to replace the Catalytic converter on my wife’s HHR…it’s showing a PO4020 code. I replaced the rear 02 sensor but it threw the code again. I was looking for a replacement but none specify the manual transmission….Are they the same pipes ? Anyone have a part number or source?

Try eBay; less than $200.
There is a difference; I think it is just where the #1 O2 sensor is mounted. Many of the cheaper ones have a bolt in the #1 bung for if yours is on the manifold.
This is the cheapest on eBay

If you buy a cheap converter it will not last and may fail very soon.

Thanks…considering the OEM only lasted 64k , I’m probally leaning towards the less expensive. My wife bought the HHR for her small business and I get to chase the gremlins 🤪….I’m going to check out the upper 02 sensor location before I order anything…seems like not too bad of a job .

For the OEM to fail at that mileage is a warranty issue unless it was being driven with the flashing CEL. Unburnt fuel is a big killer of cats.
