decat mot woes!!

28th August 2012, 22:41

Hi all, is there anyway i can get my 2003 mk2 vtr through the mot with a raceland decat manifold fitted to a freeflow middle section and backbox? Or if not, has anybody out there got a spare standard cat manifold i could buy/borrow/hire!, to fit just for the mot? Many thanks.

28th August 2012, 23:14

Is that centre section connected directly to the manifold without a decat pipe in place I take it?

28th August 2012, 23:23

simple answer no your car will not pass an mot without a cat unless you are stupidly lucky and it passes the emmissions test, i wont say that its impossible but highly unlikely

29th August 2012, 01:08

Mine read 1.25% co2 emission's without a cat haha! Limit is 0.01% so 125x over

29th August 2012, 07:27

Hi all, well ive heard that if the ecu is remapped after fittin a decat, you can get emissions set up to pass!, i will take it for the mot and see if im a lucky bunny on the day....watch this space ok guys!! ;-) ps.gandi699, yes the midsection connects straight to the 4 branch manifold without a cat fitted anywhere....just a stainless backbox.

29th August 2012, 07:36

Due to the new MOT rules etc, your car won't pass an emissions test unless the tester can physically see a catalyst in your exhaust system or you can prove theres reason for not having one O(eg, car is before 1994 or whatever it is that makes them exemp, but since this is a saxo that'll be unlikely.)

But tbh, you can buy a MK1 centre pipe and cat converter just for the MOT, it will fit straight under the car with no hassle.

29th August 2012, 07:57

I can't believe your taking your car for an mot with no cat, just setting your self up to fail

Even if you did map your car to pass an mot firstly your car would probably be so down on power to achieve low emissions and secondly you would pay£300+ to have your car run that slow?? When all you have to do is spend half an hour fitting the old manifold lol I think you've got your priorities mixed up here, just to keep a manifold....

29th August 2012, 08:23

Find a "better" MOT station tbh...

29th August 2012, 08:29

As said

Man that can..

29th August 2012, 16:27

You will just get laughed at if the man asks you if it has a cat because the emmisions is so high and you say no! As jeffchiz said just swap back to std mani cat for a bit for the sake of 20 min!

29th August 2012, 19:35

Please read my original thread posting thoroughly before commenting!! I told you that i did not have the standard manifold did i not?? Thats what im after from you....if anyone has one, and i need the mk2 manifold + the downpipe cat not the midsection mk1 cat ok.

To karlb1, so can i possibly just fit the midsection mk1 vtr cat to my mk2 vtr, therefore leaving my 4 branch in situ? As this would save hastle moving my oil filter again!.

Lo you don't have a cat so your asking us if mapping your car will help and I'm telling you it's a stupid idea, just because you don't have a cat doesn't mean the next best alternative is to spend a fortune mapping your car to run like a dog just so you don't have to buy another manifold

you asked us will a car pass an mot without a cat and the answer is no, then you asked will mapping your car make a difference, and if you meant this thread to be a wanted thread then that is against the rules and its in the wrong section,

Does yours need an emissions to complete the test? My local dont.... I do it everytime tho... :-) LOL!!!

29th August 2012, 22:15

im not trying to be a knob head but at the end of the day this thread was ever going to end in one answer, buy a cat, i persoanlly would find it easier to fit a oem manifold than mess around with changing the center pipe to a mk1 item and buying a mk1 cat and then having to sleeve the second lambda sensor as the mk1 set up wont have anywhere to plug the second lambda in to

if you just buy a mk2 cat/manifold then its all standard, will have both places to plug the lambdas in to and then its how citroen intended it to be and should have no reason to fail an emmisions text as logn as the cat is in good working order

or do what others have said and find a friendly mot center, people are under the immpression you need to have the emmisions test done on another car, in fact an emmisions test does not have to be done, its not regisitered anywhere =, it was news to me when i 'heard' about this

30th August 2012, 03:54

take a tin of biscuits to your MOT man, it will pass then.

30th August 2012, 04:07

slip a tenner into his top pocket

30th August 2012, 11:25

mine passed without a cat in the exhaust...

2 years in a row. Didn't mention anything to the garage, just took it in.

Don't see the problem people have with him taking it in without a cat? Assuming the garage offers a free retest (as most do), why go to the hassle of getting hold of an exhaust and fitting it, assuming it wouldn't have passed in the first place. Some peoples logic makes no sense - swap the exhaust IF it fails.

because a car shouldnt pass with out a cat there are things you can do to try and alter the readings but i dont know whose been doing your emmissions readings but theres no way it should pass

and AS already mentioned the mot tester can fail a car on there not being a cat present even if it passes emmisions

im trying to advise people on doing things leagally, so it will pass i dont advise people to try and get round things or bodge things, when i give out advise i want people to get the results they want to achieve, do it right and do it once

yes some peoples logic doesnt make sense at all...

30th August 2012, 12:21

my furio has passed two years ina row with no cat and stays well below the emmission limits lol

northern ireland is probably different though. pre 2002 cars dont need a cat for MOT

so, you are advising people to have a cat in their car? You don't run a decat? That's fair enough if that's the case.

If you do however run a decat, which I suspect you do, what are you on about?!

There's nothing legal about swapping a cat onto a car for an MOT, then swapping it back after? Also, at what point is anything I suggested a bodge?

I'm only suggesting that it seems bonkers to run around sourcing parts to get a car through an MOT with emissions that are okay - when he has no idea if they are or not?! Why would you not just take it for an MOT (assuming it has a free retest policy) and determine if the only problem is the lack of cat and then fix this issue in due course. If it does pass without one, then you (for no extra time or cost) have saved yourself money, time and hassle.

Your logic doesn't just make no sense... it's wrong.

31st August 2012, 17:26

Look here, i NEVER put the decat on ok?, i have just bought the car and it already had a decat system fitted so now i want to fit a cat in order to pass the damn mot.....and you're wrong....it will NOT pass emissions without a cat on so why on earth would i get it mot'd just to see before ive fitted the cat back on?

ok. I'm wrong. NHAAAAATTT - You're all idiots

I misunderstood and assumed you wanted a decat still after the MOT. I didn't appreciate that you wanted to change your exhaust permanently to grandad mode.

Further, to the bit I've highlighted in bold... I disagree, and claim that in fact, YOU are wrong. If you read my previous posts in this thread of yours, you will educate yourself on the fact that my car has passed an MOT with a decat, not once, but 2 years in a row. It's not a friend doing the tests either, just a standard garage who I have had no conversation with about the car.

Therefore my logic, and advice given, is still right. But admittedly it was based on the assumption that somebody driving a car with a decat, had fitted it for a reason, and wouldn't want to remove it permanently, and therefore in these rare circumstances it does make more sense to fit a cat before your MOT as you wouldn't be saving any time in taking my approach.

31st August 2012, 20:28

Yea I run a De-cat, but I'm not trying to get my car through an mot am I?

If you opened your eyes rubbed those two brain cells together you would have seen that I said I advise people on getting people to achieve what they want in this case its to pass an mot, and yes you moron it is illegal to remove your cat after an mot, if your car wouldn't pass an mot it shouldn't be on the road in the eyes of the law

31st August 2012, 21:09

Just buy a milltek manifold with the built-in sports cat for the best of both worlds. Simples

31st August 2012, 21:39

Excerpt from 2012 MOT regulations;

Method of inspection
On vehicles that qualify for a full cat emissions test, check the presence of a catalytic converter.

Reason for rejection
A catalytic converter missing where one was fitted as standard.

Or in other words, if the tester is doing his job properly a decat means a fail whatever the emissions results are.

Thanks for that info, hopefully Ryan might read this, as he seemed to have selective sight when I said it

Still not sure I understand you. You previously said you only advise people to be legal... which you clearly are contradicting yourself if you're suggesting they change it just for an MOT.

I completely agree with your advise when it comes to wanting a 100% chance of passing an MOT, I never questioned that. I did however question the logic, as I have explained quite clearly previously. I'll try and make it simple for you in the form of a number of points...

1) You have a decat fitted to your car
2) You want to keep a decat fitted to your car (this is where I'm making an assumption - justified previously)
3) You need an MOT (which it likely, not guaranteed but likely, wont pass without a CAT)
4) There seem to be 2 options to take...

Option 1 - Spend time searching for a relevant exhaust with a cat, find the money to purchase said cat, spend time removing current exhaust, spend time fitting cat, take car to MOT, pass MOT, spend time removing cat, spend time fitting old exhaust, spend time trying to sell recently purchased exhaust.

Option 2 - Take car for MOT with said decat exhaust fitted. (Assuming MOT station has free retest policy, and assuming you take it to said MOT with enough time to fulfil Option 1 if car fails). If car fails then proceed to option 1, which you would have done anyway. If car passes you have saved all of the effort of option 1.

See where there is no downside to my approach? With the potential benefit of saving time, money and hassle as I previously tried to explain.

Now, to address you other comments. I can promise you that I have more than 2 brain cells. I can probably, quite happily, promise you that I have more brain cells than you. Following your replies to this thread, with you failing to understand the potential benefit (with no downside) to my approach, I can quite happily predict, that I have significantly more brain cells than you.

I hope that now I've broken things down, it can be understood more easily.

Completely, 100% agree. I haven't said otherwise. Just think of all the hassle you could save if you use a tester that doesn't do his job properly and that you risk absolutely nothing, and potentially gain significantly, in trying this possibility.

As previously mentioned, I hope now that you will realise I've had nothing of the sort. Maybe I didn't explain clearly enough for you, hopefully that's been sorted now.

We are going round in circles here, saying I'm the thick one you aren't listening to a word i am saying stop going on about my car having a decat, if he asked what will give me a less restrictive exhaust, one with or without a decat I would say decat, because that is the right answer, he's asking how to pass an mot, for which you have to be legal!!! So the answer is to fit a legal mot passable exhaust hence me saying to fit a cat I'm not going to advise some one to take an illegal car to an mot center, I don't want the responsibility of some one blaming me so I tell them how to do things properly so save my back, whether or not I follow my own advise its completely irrelevant

I've owned 4 saxos and 106's and gone through 6 mot's most have failed on emissions even with a cat fitted, and guess what fitting a new cat worked every time, so god only knows how a car without a cat fitted stands any chance of passing, yes you've been lucky but having to wait for a cat to be sent through prolonging a retest is so annoying might as well just fit a new one straight away I then always sell them on for almost the price I paid for them is a win win situation, there always people wanting to buy second hand cats especially if they have only been fitted for a day

Not sure that we are going round in circles, just you it seems. I'm reading, and listening to everything you're putting - I still know you're wrong.

I don't disagree with anything you have said, I appreciate that a car should have a cat and pass emissions to get an MOT.

Not sure you have really read anything I have put. I just question the logic in your approach of fitting a cat before the MOT if you plan to remove it straight away afterwards. Do you honestly see a downside to my suggestion? and not see the potential downside to your suggestion?

"having to wait for a cat to be sent through prolonging a retest is so annoying might as well just fit a new one straight away" - this is what makes no sense. You'll have to spend the same time waiting for a new cat before going to the MOT? There's a slim chance you could have avoided ever having to "wait annoyingly for your cat to come through".

Do you really, still, not understand?

"I then always sell them on for almost the price I paid for them is a win win situation, there always people wanting to buy second hand cats especially if they have only been fitted for a day"

Is my situation, where I never had to wait for a cat, and loose ZERO money not a win win situation? Your's has a small element of not being a win win (you loose money on the cat).

I've been lucky as you say, I'm not doubting that. What I'm trying to get across to you is that it costs zero money, zero time and zero hassle in allowing yourself to be open to the same potential luck - with no downsides if you don't get lucky?

Please tell me you realise you're wrong...
