🔧 Enhanced Factory-Style Catalytic Converter Flex Exhaust Pipe by DNA Motoring for Optimum Performance Review

Sensors and converters replaced Cat didn't work. Code P0420 still popping up. I was looking at live data with a scanner. The bottom sensor should read a reasonably constant voltage of around 0.5 volts, but instead the voltage jumps between 0.1 and 0.9, simulating a top sensor. It's as if the cat doesn't exist. The part is too cheap. Don't waste your money paying a mechanic to change your cat. You end up paying double for a job if it doesn't work.

The transmitter is supplied with the gaskets required for installation, but only fasteners to attach the output to the intermediate pipe. After purchasing the nuts and bolts to attach it to the manifold I completed the installation. A little over 3 weeks later the weld on the flange started to leak and got louder with each day of use. I then checked the converter's return and…

This part fitted well with the 2013 Equinox. Addendum: 3 months later the check engine light on the…
