cat removal

:5biagree:

Just check the golden book oldskool and your right

Evening Jay

evening fella, they should no better to argue with a tester tut tut

You a tester anorl? fooking wippersnappers need to be told sometimes

i admit i was wrong:doh:, i just checked it on mot website. dont i look a plonka now. but i wasnt as wrong as discool tho

like I said I was, gave it up a while back, when I sold the garage

emissions test levels, if it passes no problem, if it dont and the vehicle had a cat when new you need one.

The way around this for a v8 is fit LPG as you can run the emissions test gas

well your wrong!! catalytic converters are a legal requirement on petrol cars from 1997 onwards. also my old 300tdi defender failed its m.o.t at my work last week due to the emisions been to high and emitting to much smoke for a turbo charged engine. if you remove the cat from a petrol car you will have to replace it for when its due an m.o.t

But a petrol engin won't pass a its emmission test without the cat if its supposed to have one, the only cars i know of thet didnt have cats fitted were susuki's cos they went the lean burn instead.

The question in post one is "Are they a legal requirement" and my answer is correct...No they are not.

It may exceed the emissions level as I stated in a previous post.

I have no doubt on that also, but as for "legal requirement" ..... So don't condem so quickly next time

Fords and Honda also supply vehicles with lean burn engines but still fit a 'cat' .

Yep thats the only one i know of and it was pre 93 so didn't need a cat if memory serves me correctly.

not sure mate on that one but you may well be right, CVH boy that was old school tuning

ok so this is fact pre 1993 dose not need to have a cat to pass an mot asked my mot tester also the lambda sensors are in front of the cat so will monitor and maintain the engine management system just fine without the cats, removing the cat will give between 5 and 20 bhp to the engine as there is nothing to restrict the engine breathing out
i removed the cat off of my 528 k reg beemer when i had it and it ran fine was faster more responsive and passed legitmatly for 2yrs before i got rid of it and my mazda 626 also ran fine and passed with no cat and that was an l reg
