Has anyone ever installed one of these on a mini? I'm looking at fitting one.

I currently have a miltek decat manifold so the second lambda sensor is pretty much not used as far as i'm aware.

I'm unsure if i should fit the kit that costs £100 and use the standard lambda sensor or go for a wideband lambda sensor and remove the second standard sensor out of my exhaust as it's rather redundant as far as i can tell now there's no cat fitted.

any information would be very useful

thanks
