De - cat !
#1
Just joined main carriageway of M6 with 35 miles of friday rush hour traffic ahead when tell tale rumbling growl from underneath , smashing :brickwall:
Limped closer to home and pulled up at local tyre n exhaust outfit . A lively bunch of lads and no mistake :eek: As lingo needed daily for work ( the joys of being self employed Confusedillyme: ) and close of play for friday rapidly approaching I felt a bit " vulnerable" to a price hike ! The hole being post cat I was reliably informed that a complete system was required for the princely sum of £ 330 ! Ouch , and have a nice weekend Rolleyes

With the amount of effin n jeffin I was doing , one of the chaps suggested choppin out the cat and puttin in a stainless pipe , job done , £ 40 . Result :thumbsup:

I quizzed the guys about emissions and passing next M.O.T. and was assured that there would be no problem :woop: Option B opted for .
Lets hope I'm not here with a tale of woe come September lol .

Watch this space !

De cats are not allowed for mot. I would suggest looking on ebay/breakers for a cheap second hand one to swap back in before the mot.

Of course I have heard people pass with de cats but legally it should be a fail, also insurance companies will class as a odification so be careful.

Quote from another forum RE decatting diesels, as they'd be allot of debate about it on there aswell...

Hi guys,

Thought you might be interested in this....I emailed vosa regarding the presence of a cat rule to ensure a decat will pass the MOT -

Quote:Hello there,

There seems to be very mixed opinions across the internet and forums
regarding the new 2012 rules for MOT testing. Now I am interested in the
'presence of a cat' rule.

The way I have understood it is that a catalytic converter MUST be present
on a vehicle which was factory fitted with one, but only if it requires an
emmisions test to pass the MOT. Now I know diesels DO NOT require an
emmisions test, just a smoke density test, so am I correct in thinking that
a diesel with a 'decat' (straight pipe in place of the original catalytic
converter) will pass the MOT like this, assuming the pipe is secure and not
leaking at all.

I ask becuase this is a very popular modification and myself and others
would be very grateful to know exactly whether this is reason for a refusal
or not.

Thank you for your time,

Tom

The answer I got was -

Quote:Dear Mr S,

Thank you for your email enquiry dated 12th April 2012, concerning an MOT.

The check for a CAT only applies to petrol engined vehicles which qualify
for a full CAT test. There will be an update to the IM in Spring which will
clarify this.

The fitment of a catalytic converter to petrol engine vehicles is mandatory
for vehicles of the specified age and type e.g. passenger car, goods etc.
The MOT Inspection Manual can therefore specify exactly what petrol engine
vehicles must have a catalyst fitted.

I hope this information has assisted you with your enquiry, but if you have
any further questions please do not hesitate to contact us again.

Kind Regards

So we're definitely fine with de-cats on diesels...... Smile

Hi A & S

If you have an MOT test ( for your vehicle ! ) in the last month of the old one, and it fails, does not that " failure " over ride the earlier MOT ?

As the MOT is only an certification of being road worthy at the time of testing and no guarantee of the same applying at a later date, is then not a later test failure a positive indication that the vehicle is not road worthy under the terms and requirements of the MOT legislation ?

MOT's are recorded electronically by DVLA, are MOT failures also recorded by DVLA and would they show up on ANR system ?

Who knows ?Confusedcratch:
