while i agree it's not the cheapest option, the time saved in installation, the time saved not having to find a place to mod a cheaper pipe, the time saved not having to wait for it to be altered, the time and petrol saved not having to go to and from a workshop and i'd say that the price of a brand name item isn't all that bad... plus you get every gasket, bolt and nut (although i'm not sure how the chinese pipes are)
