Review on Walker 81767 CalCat Catalytic Converter by Steven Lane

Very happy with purchase. 5* per piece. 1* for my skills as a mechanic. But the score is for the part. Like most people, I started hearing a knock from my 2002 Accord 2.3L LX. I saw a few videos on YouTube and it looked doable. I parked the car on the ramp and sprayed it with PB penetrant. But I could not loosen the rusty nuts. I paid my mechanic to install it. Still the cheaper way. I live in Texas and don't need a CARB compliant cat. But knowing that a CARB compliant cat would be better for the environment, I went for it. Bought the recommended pads. The shop installed new bolts and nuts. I also replaced the lower Denso oxygen sensor (234-4621) that fits in the cat. I then also replaced the top O2 sensor with a Denso (234-4620), it was easy. Revain sensors are a lot cheaper than your local car dealer. Very happy with the results.
