De-Cat Q’s (yes more of them)

[CocoPops]

I just popped into TopGear in Basingstoke to ask for a quote for a de-cat to be made and fitted.

They quoted 125notes, but were concerned when I said it had twin lambda sensors.

They said to go check what happens as they think the engine goes into limp home mode, yet all you guys seem to have them fitted etc.

So whats the scoop? I need to know how it works etc, so I can walk in there and say "yep, fit it, all you need to do is......" etc.

Also is 125 a good price?

 

[Tom]

£125 for a pipe?

is it stainless?

 

[CocoPops]

Yes, Powerflow stainless afaik as they are a Powerflow dealer.

 

[wackojacko]

Dude they are bandits in there !!! That about 1 mile from where i work. Mine seems to run better without the second sensor pluged it. Runs more rich and you get more popping.

But i suppose for piece of mind i would prefer to have two sensors plugged in.

 

[CocoPops]

So not a good idea then Rob?
Better off with a ready made decat and get it fitted myself?

 

[Neil82]

Buy a janspeed one comes with the 2 holes for the lambda sensors, it costs 120£.

 

[Scribbler]

If anyones interested i think i can get a decat made at work. I work for a firm that make stuff from tubular steel. If i know the length/size of the two flange plates and hole diameters/centres i could get one welded up and galvanised for next to nothing. I do all the technical drawing so could design it on cad then get the metal profiled. Not sure about the sensors but i think all would be needed is a tapped hole the same size as the thread for the the sensor then just screw them in. Hopefully the pipe would be straight but we can do cranked/bent pipe as we have mandral bending machines, press brakes etc.

I would have to ask the boss but think it would be ok. If anyone with technical knowledge could send me some dimensions etc i could sort some out for the cliosport members any type of car. If its not gonna damage the cars i can check fitment on my own 172 and valver. I wont be held responsible for any f**k ups though you change them at your own risk this is purely a favour!

 

[Lunner]

Likewise, i can make them for the mk1s if someon could lend me their cat for a day or so, then i coudl get one made up,

 

[McBunny]

dont worry bout second lambda

 

[Gwynny]

If it bothers you that much just have them to weld another nut in for the second lambda, It will serve no purpose really but at least its plugged in.

 

[Dansta]

mmmMMMmmmm POPPIN! NOW HOW DO I UNPLG THAT SECOND LAMBDA!

 

[McBunny]

its just a simple plug in connector

 

[Turkish]

yup, unplug it, and zip tie the cables out of the way, i bagged up and taped up the ends of the connector so it didnt get fill of sh*t before tying it out of the way

full-decats (not sports cats) are the next thing that police are gonna be clamping down on, theres another thread on here about them clamping down on windows strips, well theres some new legislation in the process of being passed soon as part of an EU directive that will make it illegal to have a full de-cat pipe fitted to any car thats being driven on the highway under ANY circumstances, even if having it fitted results in it passing emmissions test

There was something about it on one of the Lotus members sites recently, Also seen it mentioned on Sky motors programme on on a website recently

if thats the case WTF ??? if it doesnt affect emissions and is declared to the insurer who the hell cares next it will be like france where almost all performance related mods are illegal

 

[Lunner]

oh ffs, this is getting f**king stupid

Next they wont allow you a loud exhaust cus its a breach of the peace - its a f**king joke, think about all the other sh*t they could be cracking donw on, f**king drugs and burglery for one thing.

The police forcxe in this f**king country is a f**king joke!!!!!

 

[ianC]

chill out lunner, youll have a hernia

 

[Lunner]

Yeah i know, but thios sort of thing really pisses me off - i appologise for my choice language

 

[peterh2]

Makes me laugh when I read earlier that they didnt have enough resources to follow up an incident where someone who was uninsured and drunk crashed into someone, yet they have enough resources to go around checking everyone who pays there taxes, insurance, etc. for having a de-cat pipe on there car this is getting stupid.

 

[Lunner]

yup, maybe cliosport should arrange a petition.

Maybe its something that all the owners clubs shoudl get together on, if there was like a 10,000 strong petition they woudl have to do something, although they prolly wont

 

[kingJimBob]

wot about if your car was registered before 1992? surly they couldnt do sh*t?

 

[peterh2]

No, they wouldnt have to do anything, and sadly, they wouldnt do anything

 

[Lunner]

well obvously not, but seeing as theyy dont have cats, then you cant really fit a de-cat pipe

 

[kingJimBob]

1991 registered cars have Cats



[Edited by kingJimBob on 01 May 2004 at 8:37pm]



well a majority

 

[big hp]

Wasnt a legal requirement to be fitted on cars until 93 K registered cars.

 

[rich[182]]

yeh they need to get things in perspective, a de-cat is trivial alongside some t**ser driving without tax,insurance or drink driving, why cant they sort those issues out

 

[edde]

You dont need a cat as long as you pass the exhaust emmisions part of the MOT
