Emissions Warning Light

[Diablos]

If you were to have a de-cat exhaust, what would be the options available to remove the emissions warning light?
Would a re-map solve the problem?

It can be mapped out yes.

could also get a mini cat, basically a little socket looking thing that fools the sensor into thinking the cat is still there... this is much cheaper than a re map

Best to get it remapped IMO

It'll benefit from it and also, does the 200 have a flat spot like the 197 when you decat them?

I don't actually have the car yet, I'm picking it up on Saturday. I looked around the car last weekend and noticed that there was an emissions warning light on the dash. The owner said it was because the exhaust had been decatted and also replaced for a stainless steel one, including the manifold. It doesn't have sensors either, no need for them I suppose.
I've been reading on the forums that you can get an RS tuner and upload a Ron98 map to the ECU and this should get rid of the warning. Although I'm probably better off getting a custom map.

I'd go with a custom map from rs tuning for the mk3 clio.
