Check Engine Light Code P0420

I was throwing the same code. Just had my exhaust shop cut off my cats and install high flow cats. Worked and the light is still off. Cost $300 total for 2 new high flow cats, and labor

That’s really cheap if it works. I’ve been dealing with this code for awhile myself, and seems quite common on these cars from the research I’ve done. Has anyone tried the URD electronic modules to fix this? It’s supposed to be a plug and play solution and if installed carefully should pass visual inspection as well since the harness has the correct connectors so you don’t see obvious spacers, or those mini cat devices. I’m considering buying it to try, but it’s not cheap at $150, so I figured I’d see if anyone on here had good results from it.
