Remove or replace main cat
I have an '03 Maxima SE. Check engine light gives me a P0430 code which tells me that my main cat is bad. My mechanic will replace the cat for $500 or remove it (replace with a pipe) for $150. I would prefer to go with the removal option. Is there something that needs to be done to the O2 sensor if I have the cat removed?

Main cats don't throw codes. It's one of your precats that is the issue. I believe it's the precat located between the radiator and engine.
And you cannot replace it with a pipe (although that would be nice). You have three options: replace cat, pull the current cat off and gut it, or install headers. |
As TallTom said, main cats wont give you any codes.
The p0430 is the front precat, the one closer to the front of the car. |

Why pay someone when you can put headers in for that price and do it yourself its such an easy job
Headers cost $500 that I don't have. |
Sorry read it wrong thought it said replace the cat for 500 plus the pipes would be 150$

I had that code in my max and replaced the air filter and it went away. It says for the 01 max it could be Injectors Intake leak Catalyst failure Spark plug issues ignition timing issues If it's toast it's toast |

Yeah Korn's been debunking the effects of our cats since the beginning of time.
We no search, we only make thread :tardsmash |

I bought a left front cat from RockAuto.com, replaced it and the P0430 code went away. Now, I'm getting a P0021 code. AutoZone tech says I need to replace my variable timing right solenoid. Have you seen this code on your Maxima? |

JFC, you're really not going to search are you? REMOVE IT, SPLIT IT IN TWO, CLEAN IT, TEST TO MAKE SURE IT ACTUATES, REINSTALL
