Review on 🚫 Dorman 674-849 Rear Catalytic Converter with Integrated Exhaust Manifold for Compatible Models (Not CARB Compliant) by Chad Chavez

Revainrating 5 out of 5

Fixed code P0420 on catalytic converters and parts

I tried using liquid (2 major brands) and reset the code. My 2007 MDX still failed the Washington emissions test. The dealer confirmed that the code was due to a rear bank-1 failure. After 2 days of exchange, my car was passed.

Pros
  • Dope πŸ”₯
Cons
  • Some minor things
