de-cat?

[deanrankin85]

i am goin to fit my cat back scorpian system tomorrow and while its up on the four-post i was thinking of gettin a stainless downpipe and de-cat made!

but as there are two lambda sensors there, i was wondering if i would get a fault up on the engine management system if a put the lambdas back in the new decat pipe?

what has anyone else done? has anyone else had any problems?

help appreciated!

thanx!

Yes you will because the sensors will detect that the cat isnt doing its job (because its not there) and will throw up a fault code and might put it into limp mode

I think the only way is to map out one of the sensors.

 

[deanrankin85]

oh rite, im sure i know someone who has just replaced the cat with a stright bit of pipe without any faults!?

 

[M87NER]

I had mine de-catted and it didnt bring up any fault lights member

 

[deanrankin85]

a up matner! did you have your lambda sensors put back into the de-cat pipe?

 

[M87NER]

Yeh the sensors got put back in.

that's because it's not going to show with your remap....

No, this was before when the car was standard i had it decatted.

 

[deanrankin85]

oh rite

well i might be able to source an 100 cell hi flow cat and might fit that, do you think that may bring up faults?

because arnt the standard cats 400 cell?

i could just wait til its goes for a cc remap when i fit k03s that is sittin collecting dust!

 

[m0rk]

You're mistaken then.

If you decat a std cupra, it will flag a MIL lamp - no problem at all.

Had mine running for about 4 months with a de-cat with no problems at all. Both lambda's were in place aswel. Only changed it due to MOT time then got a sports cat put on after

 

[deanrankin85]

oh right! well im gona wait til i put my k03s on then do it.

cheers

ive got a 100cell cat, im in two minds whether its giving a fault or if its just the gubbed ECU

is there anyone that makes decat pipes for ibiza's? had a quick look but couldnt find any

 

[carlos200]

can get the ones on ebay for the golf gti, downpipe and de-cat but may require some welding i think..

 

[Myki da Pyki]

I wouldnt recommend de-cats anyway. Yes they are less restricted than cats but eventually you'l have to change back to the standard cat or a sports cat so not much point

i read that std cat are 600 cell

Why? Obviously for MOT reasons; but any other reason?

Management lights, limp mode, running issues. Road side emissions tests. Plus the noise.
