View Full Version : cat on a K reg
was told of a mate that i dont need one. anythink under L dont need one.
this right.?
Nope if its a K reg it should have one, if it had one originally then it should have one but then again if it was an early K then it might not need one.
Legislation came out saying they should have one in 93 so in theory if yours is earlier then you might not need one!

I see.It has got one on it, ill just take it off then if it needs it for MOT then ill put it back on :)

i thought it was late 92, therefore any K reg cars. but seeing as the engine was originally designed in about 1820, it wasnt originally designed for one, and it may have been registered late, therefore not needing one. basically it all depends on what your tester says come MOT time

the emisions test in the mot for late 92 onward cars is harder/requires lower emisions! just keep the cat in the garden shed for the mot test lol
Whats the reg number bud, pm it if you like!
Mine is late 91 iirc and spi, it had a cat fitted, but ofc it didnt need one.
your pm box full mate lol

They do as mine is a 92 K and was meant to have a cat test as it had one originally.
Sorted now bud try again
lol

pre august 1992 need a cat.
Apparently the legislation came into force in 1993 but i cant find an exact date, yours however is a late K reg.......
Date of First Registration 06 11 1992
Btw your reg aint far off my old XE, mine was the same but 671 as the numbers!

this is interesting, its a bit vauqe regarding dates if you google it, must depend on engine size also?
Yeah ive been through a few different links and some say 1992 and others say 1993 so im very confuddled lol
my j plate hasnt got a cat

my m.o.t tester put my nova on another test as my cat got binned lol
You really dont wanna be advertising that one bud as that means you have got a dodgy mot as your vehicle was passed for emissions but never actually had the test which is very illegal!

IT IS A MYTH THAT CARS NEED A CATALYTIC CONVERTER TO BE FITTED TO PASS THE MOT.
There is no mention in any documentation (ie the MoT testers manual) that states a catalytic converter is required. The manual mere sets emission levels which have to be achieved if the vehicle is first used after a specific year. Some cars may achieve the required emission levels without a catalytic converter, some may not, so it simple boils down to emmision levels nothing more.

agreed :thumb: some decat cars may fail though! depends on the state of the engine! my 93 nova gsi only just passed, with a tweek or two :D

true, my nova a k reg thats ment to have a cat, mot tester was telling me it needed one and i told him i will if it really needs one and fails, it passed last year with no cat with flying colours, dont think it will next time like lol ,
one thing i tried to find out is what if the car is say k reg with limit 0.30 and has different engine in (older) that would of had a limit 3.00 or even the other way round does it go on the year of car or the year/size of the engine ?
Any vehicle registered on or before 1st August 1992 doesnt acutally need one by law. Anything registered there after does.
See Loggys post, NO cat before 1995 NEEDS a cat fitted, IF it can pass emissions for the engine/vehicle year....
A car that runs the post aug 1992 emissions on the mot machine Wont pass the test without a cat fitted, as it just cannot get the emissions low enough....
Any vehicle registered on or before 1st August 1992 doesnt acutally need one by law. Anything registered there after does.
Is that definitely on or before, or before? As mine was registered on exactly 1st august 92, although it all seems pretty vague as to whether or not it goes on car or engine and also whether it's the date the engine was built or the date the car was registered.

When that has come up before its always been said that if you can prove the engine year and that its pre-emmionsion crap then it wouldnt need to pass the cat stuff.
If that makes sence. Im a bit tired.

Is is a carb or injection? It goes on the date the car was registered IIRC?

The 1.2i engines come with a cat and the 1.2 Carb engines don't
Any car registered after November 92 needed a Cat to go through an MOT IIRC...
I think my mate's silver Nova 1.2i is Nov. 92 and he needs the cat for the MOT...
i got my 2003 corsa sxi through without one......

my k reg got mot'd and he did the cat test first as the aproximate date of first use was in august the car didint stand a chance every limit was over but after finding the service book( all from vaux lol ) it said pre delivery inspection was in july so got to do the pre cat test and it flew throught it the limits are considerably higher if you can prove its not ment to have a cat

FFS how many times.
NO CAR - REGARDLESS OF AGE - REQUIRES A CAT TO BE FITTED TO PASS THE MOT
It just needs to pass the emmission test. True most cars wont pass a the emmisions test without a cat but there is no where in the MoT testers manual that states a car can be failed on not having a Catalytic converter.
hence, as i said, i got my 03 plate corsa through without.

..... Well said loggyboy.
Note also that if you retrofit an OLDER engine (and get the V5C reg document changed to represent the alteration in engine number) then the emission test is based on the emission law in force at the point in history that the ENGINE dates from. Not the car.
lmfao every time a thread like this gets posted it usually ends up as loads of pages, all with a different reply lol
Loggy is right. Catalytic Converter is not PHYSICALLY required on ANY car. However, cars dated >08/92 (with some exceptions) have to pass a more stringent emissions test, of which most cars will need to utilize a cat to pass.
(and get the V5C reg document changed to represent the alteration in engine number)
Engine number alone isn't enough, you need to prove that engine is of xyz date (i.e. manufacturer confirmation).
Well the engine I'll be fitting is a H reg, as long as the retrofitting engines point is correct.
1st aug 1992 is cut off period
so if it was registered before this date legally it does not need a cat fitted

No car legally needs a cat fitted though.

Thanks for the correction Razorjack. I have thought of a possible dodge for proving the date when fitting of an older engine. I would hope that the V5 records for the (engine donor) car would suffice as evidence as the tester would be able to match up the donor engine number. My tester would certainly be ok with this (as long as the red tape would allow him to pass the vehicle in such a situation)
