I have a couple questions regarding long tube headers and shorties, so my catalytic converter is failing on the driver side, it's got only a p0420 code no other code. I've changed out the sensors still came up. So I'm stuck in the middle between removing them and getting long tube headers or replacing them and also getting shorties installed in the process, but if I install long tube headers do I need to get the truck tuned? Or if anyone has had then installed did any codes pop up after the installment.
