Review on 🚗 Dorman 674-439 Catalytic Converter with Integrated Exhaust Manifold for Honda Models - Non-CARB Compliant: Product Review and Buying Guide by Robert Aiono

Fits my '99 Honda Civic DX. However. The bottom "o-ring" that connects the bottom of the cat converter to the exhaust pipe was not included in my kit. We've looked up and down but haven't found a round o-ring. To complete this project without further delay, I simply used an old o-ring. I wasn't very happy about it, but I didn't want to delay this project for a seal. I could complain but I wanted it done as my exhaust manifold had cracked front to back and needed to be replaced immediately. By the way, this o-ring is included in the pictures you see for this item and MUST be included in the package. That is the reason for 4 vs 5 stars. Hopefully my old seal will hold up.
