is it worth decatting the standard exhaust?

[smoggy mark]

Can any old exhaust place fab one up?

would think so they just remove the 2nd cat and put the decat in place.

will it bring the immisions light on?

If your just removing the 2nd cat it wont do as the pre cat is still in place..

dont be to sure on that the second lambda sensor monitors cat efficiency and can put the light on

 

[ryan197]

in some cases it brings the light on and some cases it doesnt, it luck of the draw

 

[smoggy mark]

yes like ryan says some do some dont.

 

[greeni197]

It must work at a ratio of 1:100 of the light coming on then.. I've never known of it to happen to anyone not even mine.

 

[ryan197]

theres been one or two that have had the light come on, one or two that have failed emmisions, ans some that have the light flash now and again in warm weather
