im under the impression if you remove the cat internals the second lambda will flash an error at you. as this is the cat operation sensor. i dont believe its a good idea/expensive mastake-a to make-a!
as far as i know no-one except me was running a fully working decat as my aftermarket setup did not require the second sensor. other than that BURT150 has probably gotten closest.......................
Of course removing the cat internals will through up the EML light - its effectively a decat.
However, you and BURT150 are not the only people to have an error free decat system in place.
Mine is completely EML free since the 27th of April last year. You just need to purchase one of these for about £25 from ebay.com. Decatting is a great mod for the 2.2, not only is it cheap it really livens the revs up and definitely pulls harder.
