P0420 Catalyst System Efficiency Below Threshold Bank 1.
So with this code coming on intermittently, I thinking the catalytic is probably getting old and tired like me! Truck has 315K on it with regular maintenance including tune-ups.
These are very expensive to replace so what if... Or could I... replace with straight pipe and then somehow reprogram the ecm to keep the code from appearing? Or is this a loss cause? Trying to figure out a way around replacing them of course.
Thanks
