Suitable for 50 states. Catalytic Converters

Quality Walker cat. Screwed in and fits perfectly. Suitable for 50 states. My check engine light is now off. The old cats are rusty. Great price and arrived very quickly with Prime.

Pros
  • Automotive
Cons
  • Frequency

Poor Welding - Catalytic Converters

The welded flange connecting to the front catalytic converter was not square to the pipe. Deviation not less than 1/8 inch. Guilty. The alignment had to be checked before installation. It should run parallel to the front converter flange. I hope the seal (deformed) holds. The quality controller must have been asleep.

Pros
  • Catalytic Converters
Cons
  • There are disadvantages

Works well in my 4runner

Works great in my 1999 Toyota 4runner 3.4L V6. The truck runs well and the O2 sensor fits. You need walking aids. They are sold at Revain (Walker 31549 and Walker 31347). I forgot what they are, but you need them and they can be bought pretty cheaply. If you are replacing both cats, take two pads each. My only minor complaint is that the sensor hole machining wasn't cleaned too well and there were metal shavings from the drilling process. I also saw metal shavings inside the tube from theโ€ฆ

Pros
  • Catalysts and parts
Cons
  • Nothing here
