such as the GGR version, are there any problems fitting to my02 and what about performance... the main reason I am thinking of spending the extra money is to stop the engine check light

 

No real problems fitting to the MY02. You can't be 100% certain that it will stop the CEL; there's still a chance you'll get the light even with a sports cat in the downpipe. Unlikely if you keep the up-pipe cat, a bit more likely if you decat the up-pipe. And de-catting the up-pipe is well worth doing.

You can stop the check engine light from a full decat with a little box of tricks from various people, if that's your only issue. The one thing that a sports cat can do and a decat can't is keep the emissions legal.

 

I'm still researching fitting a sports cat downpipe and replacing the up pipe for my 02 WRX.

Just a quick question on this - if the CEL light did come on in with this setup, can it be easily cleared without a trip to the dealer? I can live with it coming on occasionally so long as I can 'switch' it off again.

 

It can if you buy a SECS 1004 monitor, you can reset the ECU and clear all fault codes.....

 

Thanks, but this is my only problem with Scooby ownership. The goodies and toys available for them are meaning my bank balance just keeps going down!

 

You can clear minor codes by turning on the ignition, going back one click, ignition on, back one etc 5 times. Then start the car.

This doesn't do a full reset, so learnt correction tables (and full performance) are retained.

 

have a word with pat about a cheap box of tricks for removing the CEL.

 

cheers guys, has any one on this site ever had problems with the full de cat, as I have been advised by a well respected company not to have it done due to problems, ow and the scooby garage say its a huge no no, but thats no suprise
