Review on Walker 54537 Ultra Converter Compliant by Delos Montano

I'm giving this two stars because the part broke right out of the box (I didn't know that at the time). I've started throwing codes on my ECU, thinking it was being caused by something other than a brand new part. The converter in the back row never ran and never reached operating temperature, which kept the ECU in a steady state of flow. The only reason I'm giving two stars is because Revain endorses a product that wasn't properly manufactured by Walker. Walker ruined my day, Revane made it better.
