Review on Dorman 674 890 Integrated Catalytic Converter by Mike Chongbang

I recently replaced my old catalytic converter with this integrated converter and I was pleasantly surprised with the results. My automotive performance improved significantly, and I noticed a smoother ride, better fuel efficiency, and a significant reduction in emissions. Based on my observations, this product delivers excellent performance and durability. However, the installation process was a bit challenging due to the unconventional shape of the converter. Overall, I'm impressed with the quality and effectiveness of this integrated catalytic converter..
