    There will be an improvement in both power and response from the throttle. not huge gains maybe 3 to 8 bhp and you get more turbo "whistle" when accelerating, can not say which is the best but make sure its a full bore pipe and not a restricted pipe as some are.

    thanks for that would you know if it would cause any harm to the turbo over time because of less back pressure thanks dave

    yup as already said it is legal to decat a diesel. petrol engines are tested on C02 levels etc whilst diesels are tested for smoke.

    it should just be a piece of pipe with a couple of flanges welded on either end or something to that affect. the price may be because some are just mild steel and others are stainless? i'd go for the stainless if you can.
