🚗 Dorman 674-889 Catalytic Converter & Integrated Exhaust Manifold for Chevrolet, Pontiac, Saturn Models - Non-CARB Compliant Review

Perfect fit. Exactly what I needed. Factory quality with a slightly smaller catalytic converter for easier installation and more room to work.

Perfect match for my 2006 Malibu. The dealer advised me to buy an AC Delco because they said the car wouldn't accept anything else. I had it installed at a local shop and had no problems. Power has been restored to my car and I am very happy with the Dorman.

After only 3 months it has already torn in several places. There seems to be no return. From what I've read, Dorman lets you roam around too. Didn't realize I had to buy for such an expensive part and extend the warranty. Don't waste money.

I didn't like how I had to modify the item to fit when it should have been an OEM style replacement part. More work had to be done than was required for the repair. Someone needs to speak to the people in the casting and casting department. After working with the metal a bit, it fit like a glove. Not at all satisfied.

For those who live in countries with strict emissions laws, I live in New York and it has a Gm OEM label on it. Not sure everyone will have one but he cleared my codes and I'm a happy camper. The one I removed from my machine should never have been installed. It was an aftermarket that couldn't be sold through a dealership in my state. I hope this works for you!

Installed on a 2008 Pontiac G6 2.4L. Fits great, no modifications necessary. The power limit returned and the sluggish acceleration was gone. FYI GM has extended the catalytic converter warranty to 10 years or 120,000 miles. The dealer wanted $999 for that part alone because I had $136,000. I would suggest an E7 star socket, ratchet U link adapters and an O2 sensor socket.

Cheap defective item. We had a code P0420 and that's why we couldn't pass the emissions test. Bought and professionally installed. The code stayed disabled long enough for us to overcome the outliers, but within 2 weeks the code reappeared and reappeared even after multiple code resets. A year later we spent a few hundred more on the mechanic's product selection and the check engine light hasn't gone off since. Choose another brand.
