my exhaust warning light came on today.. I have changed the exhaust from standard (sports cat and milltek cat back)
I know its expected that the de-cats cause the light to come on but should it be expected from a sports cat too?
I thought the exhaust sounded a bit rattley the other day but it was fine once the engine/exhaust warmed up so I thought nothing of it - perhaps something is loose? (I'll go check when it's cooled down -anything specific to check for after the lambda sensor?)
