Decats

Taking up on sleepers reply

 

1993 cars on are required by law to have emissions to a certain level. This has best been achieved by fitting cats.

For an MOT or a roadside emissions check, so long as the vehicle limits are below what is required by law then it will pass.

Roadside inspections can be challenged because unless your car is fully warmed and the ambient temperature above 5deg then the results will be invalid. Other factors also affect the reading eg a windy day. In the workshop for the MOT it is a controlled environment and more accurate at obtaining the MOT standards.

I had a guy ask me about roadsie checks once and when I told him all the variables he was astonished. Turned out he was a local magistrate and was getting these things in his court. Said he would admonish all he saw. That was 5yrs ago now but still the variables are there.

A cat missing in itself is NOT an MOT fail.

I had an old 1984 525e with 150k on the clock and it would pass a cat MOT test, no problem.

The cat takes about 10% power absorbtion so taking the thing off definitely releases more horses.

ive got a 1991 j reg e36 with a cat fitted and i told last year by mot station that cats not mandatory until 1993.

right, this is daft, for a "senior" member to come in on a thread and attack some one, is crap.

i drive a bm on the road, but i also track an old mk2 golf...why because its so hard to get good bm track parts.

additionally cat are post 93 only so any one with a pre 93 car can do what they damb well like with there cat, like my car a late 93 model, additionally i fitted it and found that there was a noticable improvment. i only no longer have it as i got a full s/s system at a knockdown price.

so senior member as far as i am concerned you can take your abuse and shove it up your exhaust till it hits your manifold. you re-mould buying tool.

Best of luck Andy, dont give up on us! most of us are really nice people.

 

cheers

I thought this thread was dead & buried but it appears not.

I take it this is directed at me? Why does the number of posts I've made have a bearing on the issue? Wind your neck in "junior".

Indeed, owners of such cars can "do what they damn well like with their cat". For later cars, a cat is a legal requirement.

Hmm, very succinct. Ignoring the actual facts raised in this thread, everyone is entitled to their opinions. I've expressed mine, you've expressed yours (such as they are). Whilst you can disagree with opinions, the facts are harder to ignore.

I notice you still have not addressed the legality of a post '93 car without a cat.

Never bought remoulds in my life. I assume this childish name-calling is some form of insult? Grow up kid.

Your command of the English language & creative use of punctuation was rather amusing but it was your username that really made me laugh. Steel Donkey? You've chosen a very apt name for yourself. Apologies to donkeys everywhere.

ok, I've got away with it so far, and both non-cat MOT's I've had have passed the emissions fine.

I'd probably get clobbered on a roadside tho' so Ill be keeping my head down!

Anyone been checked for emissions/cat on a roadside? I've not seen one as yet but heard of them....

neither was I until I read a posted reply on the old/new(?!?) forum - can't remember who or where or when tho'!!!!

I believe they are similar to the commercial checks done by the VOSA & old bill.

As this is important to me (and others no doubt) it would be good to have confirmation on if they are being done & what checks are made.

Randomn checks can be conducted by VOSA or the ploice, but mainly VOSA. The local authorities also have the power to carry out spot checks on emissions and VOSA have trained a number of authorities in the procedure.

ANY vehicle can be inspected by VOSA be it for emissions or for roadworthyness check. In Scotland the police are needed to stop the vehicles but in Englandshire VOSA have the powers to stop as well as the police.They use the Ford Galaxy vehicles.

The standards are the same for the roadside as they are for the MOT. And that brings me back to the issues of the variations that can happen at the roadside.

Plus I agree and have siad that a missing CAT is NOT a fail but it may fail on the emissions. It doesn't necessarliy mean it will, depending on the tuning of the engine and its mapping. Like I said before I could get a B plate 525e with 150k on the clock to pass a CAT MOT standard and that was definitely a non cat engine.

I was led to believe that your policy would be invalidated by any modification that was not declared.

Also the way insurance companies seem to act these days im sure they would find some way of linking the modification to the accident.

They may not get away with not paying out but you would have to fight them on it. They would claim that because the vehicle had been modified and they had not been informed then the policy had been invalidated. If you check your insurance documentation you will see that there is a clause that states' failure to disclose any modifications to the vehicle will result in the policy being invalidated' or words to that effect. In all likelyhood the insurance ombudsman may well force them to pay up but not without a fight.

yup 100% agreement with above, i was simply saying that a non declaration does not automatically invalidate your policy, it certainly wont help and i am not for one second advising it.

now where's that bus queue.....
