I suspect my cat/s are gone, Based on advice and Noise and the rest of the system is bent! My car was first registered in August 1993. i want to know what my options are for a replacement from the Manifolds to the rear bumber. Must I fit new cats or can I have a straight through system? Also can anyone recommend a exhaust supplyer? |

It depends if your car will pass the emissions test with or without cats. If it passes without them then you will get away with it. Problem is it's an expensive experiment.
Where are you based ? |

Swindon Wiltshire, I have been told that my emmisions will suffer as the lamda probes are required to weaken the mixture? so if the new pipes cant use the probes then I'm shafted. |

If you fit replacement pipes, the lambda probes will still be fitted. They will have a threaded boss for the probes. if not then the pipes are no use.
One problem may be that the lambda probes will be unable to compensate for the emissions from your engine.
All the probe does is send a signal back to the ecu with a value for oxygen content in the exhaust gas. If it's too high the mixture will be increased. If it's too low the mixture will be weakened. If the probe sends back a value to the ecu which is out of range, the ecu will be unable to adjust the mixture sufficiently to satisfy the emmisions.
This will only happen on an engine which is not running efficiently or has some other problem.
On an Aug 93 car, the emissions requirements are fairly relaxed and your car will probably pass the tests without the catalysts. For suppliers, I've heard good stories about Longlife and Milltek. You may want to contact Dialynx who are near you. |

There`s a good chance your car will fail the MOT if the cats are missing as all post 92 cars should have them fitted. |

A 1992 car on a J plate (registered on or before 31 July 1992) does NOT need a cat, a car registered on or after 1 August 1992 (i.e. K reg) NEEDS a cat.
Phone the Vehicle Inspectorate (now VOSA) MoT hotline for confirmation (like what I did). in the phone book.
If you take a post August 1992 car for an MoT without a cat, it will surely fail, as the standards are different.

If you are in Swindon, I would try Longlife, as they are in Bristol (J14 M5). I had mine done there (100 92j 2.3 quattro) and am very pleased with it.
Total cost was about £450 including removing the cat.

This information about cats is wrong.
It is NOT a legal requirement to have cats on post 1992 cars. The emissions requirements changed in 1992 at which point the vast majority of cars were supplied with cats to ensure they would meet the new regulations. Note I said vast majority - there are Peugeot diesels out there with no cats and they were made up until about 1997 like this. there are probably other cars as well - just used that as an example. |

Longlife in bristol 0800 27 999 00 quotedme £350 inc vat and fitting for a SS Freeflow system, from the cats back, with my own choice of tail pipe. this includeds a transferable lifetime warranty. Cats are £260 each new or £70 each used, so I will try my luck with used. they say the job will take 4 hours and can provide a courtesy car. they are near Cribbs Causeway, but bristol zoo will win if the weathers good!
Let me know if you would like to know how I get on. |

From VOSA:
Under the MOT testing scheme, vehicles first used between 01/08/86 and
31/07/92 are permitted to have a non-catalyst test.
First used date for emission test purposes is the earlier of either:
the date of first registration or
the date six months after manufacture.
Vehicles first used between 01/08/92 and 31/07/95 will either need a
catalyst test to specific limits set by the vehicle manufacturer or , if
not provided, a non-catalyst test to set limits.
Vehicles first used on or after 01/08/95 will need a catalyst test either
to specific limits set by the vehicle manufacturer or to set catalyst
default limits. |
