I am kinda laughing, cause when I first was looking at the ST's every one said the car was "Impossible, or going to be very hard for aftermarket". What we have Two turbo's already and looking at possibly dozen more if they go threw with this lol. I mean the design shouldn't be to hard to make, just figuring how much of a curve would be needed in the pipe. Turbo probably sit at a rather odd angle tough. Whats cool about our heads with the integrated Manifold is, they are suppose to 0 Restriction, until you build the heads up with bigger valve and more aggressive cams, then might have a restriction issue, but Build a single tube pipe to adapt turbos, is much easier then build heads that make all the exhaust gas hit the turbo at once. So in theory this should be a better more power gain setup in a way.
