Hello I need some advice- my 96 disco's cat has gone bad Ive gone to all of the muffler places and they say they cant help- is it possible to run a straight pipe and bypass the cat? what about the oxygen sensors? This is very depressing as I do not have a spare 1000$ burining a hole in my pocket. Thanks. |

Any muffler shop should be able to put a catco converter on for about $150 |

The muffler places I have been to both chain stores and independents, say that it is a dealer only part and they cant get a price. They seem scared by the two oxygen sensors. I found one guy who will install it if I find the part- I found one at atlantic british but it was 500$ is there any thing I can do to rig it? |

I would just by pass it with some cheap pipes from autozone and then if your ce light comes on spend the 149 for the OBD II computer because sooner or later your gonna need it. When you have that monitor that to see if you have other problems, but you will most likely have a emission warning from your new OBD II comp. pipes less than 10 bucks and the comp at autozone is 149. less than 500+ |

That sounds like more what I have in mind since unfortunately there is no warranty on the vehicle. So by passing it will not harm the vehicle? Thanks. |

My passenger side cat went bad and caused a knocking/pinging noise a few months ago. A local welding/muffler shop replaced it for $150 parts and labor. You may need to look around a bit but someone should be able to cut out the old cat and weld in a new.

The reason muffler shops are telling you that is because everything after 1996 have to have the OBDII compliant catalytic Converters on them. The older universal Cats are only for 1995 and older vehicles. LR cats are available new from a LR dealer or a lot of aftermarket suppliers like XKS, but they are VERY pricy. You can also get them reconditioned for about 500 dollars. There are universal OBDII compliant cats available, but they are not currently approved for Land Rovers. Depending on the application, we normally sell them installed for 250 to 300. You want to becareful installing a OBDI cat on a OBDII system because I've had them set off the check engine lights from the 02 sensor. Email me if you need any further help or have any questions.

On a 95, what would happen if you just replaced the cats with straight pipe? On the 95, there are NO O2 sensors after the cats. |

Cut both my 93 V8i Cats out. (after the pre Cat O2 sensors)and more rumble now than before. Maybe a little increase in power I think! Better check re emission control law at your end. No emission laws here in NZ yet. Cheers |

I have a '97 SE7 with 107000. Went to a custom muffler shop and used high performance MagnaFlow CATS for replacement. OBDII compliant and all. Approx $200 for each CAT and approx $200 for labor. $600 total and my mileage went from low 14s to 16-WOW. You can actually feel the difference in power too. TX Brent |

What exactly do the O2 sensors do other than sense oxygen? Are they really important to the vehicle running well? We dont have vehicle inspections here in Indiana so Im not all that concerned about cutting out the cat but I dont want to hurt my beloved disco either. |

Janaka, great link to that 80000-mile emissions warranty info. Just last week, the converter on my Audi failed. It was replaced under Federal Emissions Warranty (the car has 75000 on it.) Audi picked up the entire $1500 charge! And the dealer moves to another town today, so the timing couldn't have been better. Alexa, the oxygen sensors feed back data to the fuel-injection computer. It seems that, while my car's converter was leaking exhaust, it was running way too lean. |

OK. I have a 97 Disco and something is doing some serious ratteling when I am at idle. From reading the above comments, its obviously my cat catalytic converters. So, im not sure what OBDI and OBDII mean. Maybe someone can fill me in. What would be the best route to take in repairing my broke ass Discovery? Do you have to replace the O2 sensors at the same time? Thanks. |

Robin, Also check your heat shields...They rattle sometimes and can make one think they have bad cats. As far as replacing the o2 sensors during cat replacement its not a bad idea...especially if they are original. Its a heck of a lot easier to replace with the y pipes off as well.

Ahh, heat shield. I'll check that out. So im guessing new cats + O2 sensors = the selling of a kidney. Let me ask this, does it harm anything to keep driving it if it is the catalytic converters? Thanks again. |

Sorry for the potentially bad news, Robin, but my '95 made the same noises and it was one of the converters. The baffles come loose. Don't forget that Emissions Warranty! |

PS - OBD is the Federally-mandated Onboard Diagnostics processor and interface. All Land Rovers '96 and after have OBDII. |

Yes, oxygen sensors are important for more than just emissions. The computer uses the oxygen sensors to lean the engine, and if it is not getting a good reading then it will run the engine overly rich (because running too lean will damage the engine). Good oxygen sensors can definitely increase your mileage. |

Kind of a FYI.. Everything after 1996 has to be OBDII compliant. 95 and older are OBDI compliant. There are universal cats available for both. The OBDII cats usually run about 200 to 250 installed and the OBDI universal cats usually run 89 to 150 installed. Can you us a OBDI universal cat on a OBDII vehicle. Legally no.. But I've seen them used with mixed results. The wrong cats MIGHT cause the "check engine" light to come on. I stress MIGHT because it doesn't happen everytime. Good luck.. |

You dont have to replace o2 sensors when replacing your cats. You can replace with catco. $150 installed. Jesse Cielo buy house can do yours if you need one. I didnt need to change out o2 sensors. |
