Review on πŸš— Walker Exhaust CalCat Carb 81744: The Ultimate Direct Fit Catalytic Converter Solution by Peris Auditore

Revainrating 5 out of 5

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 the machining process. It was annoying to have to clean it before screwing it on.

Pros
  • Catalysts and parts
Cons
  • Nothing here
