hi everyone reason for this post is im trying to find out peoples views and experience with the mini cats and the odb cat delete simulator to stop the evil engine light from coming on. do they really work. I know that novitec capristo and akrapovic all do the odb cat delete simulator I would love to hear peoples views on these products. aswell as the mini cats do they work and which ones to buy. I dont want to tune my 458 because its still under warranty i have spoken to my local Ferrari HR owen garage they dont have a problem with me fitting the novitec system they said as long as the engine light dont come on they will turn a blind eye to your exhaust system. I would love to hear peoples views thank you very much oz.
