   As the title says realy, ive found one and it comes with the hole for the lamba sensor....wont this just throw up a fault code of CAT failure?
   
   Also, is sleeving the lamba sensor outside the exhaust realy necessary?

   yeah but i thought it wud come up with a code if the sensor doesnt detect anything? because it would think its faulty?

   If its a 2 lamba set up its about the difference that the readings get.
   
   First reads pre-cat dirty, second post cat clean (hense the sleeve makes the ecu think the cat is working properly!)

   Yeh, the ecu just thinks the cat is working very well. Is the sleeve just for protection then? while its out of the exhaust? does it need airflow?

   Put a sleeve on mine and not had any probs for last 3months! As sensor not all the way in the cat it's only gettin some of the (dirty) air like it normally wld so doesn't bring the light up! Simple but affective idea for decats!

   Wait...so its a sleeve whereby the lamba still goes into the exhaust? I thought the lamba just got left out of the exhaust and sleeved up.....

    Na a sleeve where the sensor screw into that then you screw both into the decat so the sensor just sits out the decat a bit more! If you leave the sensor out it will pick up the post cat sensor either not working or the cats faulty and bring up the em light and run juicy as which mine did before I plugged the sensor in from the manifold aftr fitting 4-2-1!

    Got mine off fle-bay but kam do them aswell, think they bout £18+pp but the best thing to do, an a piece of piss to fit! Make sure u dnt turn the ignition on though with sensor disconnected or fitted as warnin light will come on and need resetting, jst a ball ache!

    Found one on kam, but im not sure how it will screw in....the lambda goes into the sleeve, but surely the sleeve wont go into the exhaust theres this on ebay that you have to weld on, and the kam racing one seems the same....

    They should screw into where the sensor normally goes into just like the sensor does!
