My son's 05 had both sides stolen 03/2021 in College Station,TX(where A&M is). National chain wanted ~ 4k and two weeks to replace with Mopar complete assembly. Local independent wanted only ~1200 using universals, so we went with that as a stopgap. Vehicle has been running fine AFAICT, but has had CEL for P0420(I think) for bank 2 post cat o2 sensor per OBD/bluetooth scanner ever since. I told him to keep an eye/ear on performance, thinking harness got tugged on or cut during theft.
Fast forward to 03/2022. He has since moved to one of the few Texas counties that requires annual emissions check with safety inspection, and we cannot get it to clear the code with new downstream sensors both sides. It's tight quarters down there, even for the downstreams, but there was no apparent disturbance of the wiring. Different national chain that issued the emissions fail blamed aftermarket cat's/welding thereof. Said stealership would charge ~ 5k for replacement with Mopar complete assembly but they would do it for ~3k and honestly probably not worth it. We are now checking into getting some sort of exemption or selling to someone in a no emissions test county.
