how to remove a cat? Mk 2
 

how to remove a cat? is it a problem with the second lambda sensor?

hacksaw....

undo the bolts

is what a problem ?

lol need to know a bit more mate about what you are trying to do or whats wrong exactly

or...... just twat it thats how i got mine out.....

Take it your on about a mk2 vtr? With the cat in the manifold?

his name has vts in it

So, could be for some one else? His last name might be vts :)

the problem is, what happens with the second lambda? will the engine light be on?

yes you need a sleeve for it

gmc sell these

Could buy a sleeve for it, i have one on the way for mine, you just screw it in and tie it up, this should stop the light from coming on :)

If you dont want a sleeve just tie it up out the way, but yes your light will be on!

will i lose performance if the engine light is on because of lambda

lmao

Have you had a look under the car?

think the nuts come off easier when the engine is hot as it will expand and be easier to undo

either warm the engine up or use a blow torch, id rather run the engine though :y:

no mate, not if your putting a stainless steel manifold on. if your not and your just taking your cat out then yes unless you bung up the hole where the second lambda sensor comes from

I have a gmc 4-1 manifold and there is no hole in that to put this sensor there fore the light is on untill i get my sleeve.

the cat is under the car ;)

I'm pretty sure when my ECU light has come on in the passed it's wound the ignition timing back in a bit

just get a replacement pipe then

all you need is a decat pipe then mate in that case!!
