Hi all, just bought a de cat pipe, the one after the downpipe on a newage. I have been told the CEL light will now stay on. How do i go about rectifying this, is it a resistor i change or something else etc?

Thanks for any advice in advance

Something called a "cellfix" is what you need mate, around £25 fitted from memory

willsy369

any idea where i would get one of these? and how it gets fitted. Thanks for the info

Not sure where your local Subaru specialist is mate,

It replaces the ***** probe that goes in the pipe, so the ECU does not detect a problem.



***** = cant spell it aint gonna try

willsy369

do you mean the lambda sensor? and my local dealer is a german one so try to explain this to him will be fun!

I think that may be what it is, Im sure someone will be along to explain more accuratly, but its a cheap fix


Good luck mate

Hayward & Scott do a fix for about £10.

What de-cat pipe did you go for?

willsy369

the one after the down pipe, either the second on sti or 3rd on wrx.

not sure if mine has 3 though so could just be my 2nd(bug eye had 3 i think not blobeye??)

either way its that one i have bought!!

You should read this thread.

The guy who posted it was a genius, of course but it's a simple enough fix and should work for anyone

changed the 2nd cat om mine the other day my05 wrx and had no problems with it.

That sounds promising then! cheers Phill.

What difference have you noticed at all with it removed?

Do we only have the 2 cats also on the 05wrx? i have had many different sugestions about this!

Sorry to hijack, but if I understand this correctly, even though the decat I have has a thread for the lambda sensor to be fitted in, I will get a CEL and fault code when I replace the cat (3rd cat on a WRX) with a decat?

Here is a reply I received yesterday from Hayward & Scott as I ordered the decat and centre pipe from them for my WRX03.

Your cel light will only come on if you remove the down pipe with 100 cell
cat in. By removing the 2nd one this will not bring the light on.

Sounds good, I'll let you know what happens when I fit the decat, but that's put my mind at rest

Prodrive get around the CEL by having the boss for the 2nd Lambda about 1 inch longer on the 3rd decat section.
I believe it gets the Lambda out of the increased exhaust gas flow to stop the heater being cooled too much (after fitting the Prodrive 100 cell sports cat) and throwing the CEL.
These CEL fixes can be bought separately or even made by a friendly lathe owner. All they are is an extended boss with a female and male thread at each end. The electronic fixes don't always work and are a pain to fit.

ive changed the backbox and centre section on mine as well and yeah the car picks up alot better, theres 2 cats on the newage wrx one on the downpipe and there is the 2nd cat after it. i wanted to change the downpipe too but looks too much hassle to do it.
