hks 2535 no good for 260 to 280 2835 or 3037 and higher in hks better brand plus turbos in that brand are well known in the 2500 and up bracket turbo alone then the lines well est 300 depends what and where you get, custom dump well another 600 for a good split dump/front pipe, fitted that can vary as well pends if you do it yourself, oh and the neo not sure on manifold setup theres the estimate for you
