The yank manifolds only go through 50degrees turn or something like that.
Ive been looking and discussing with some americans for a while at manifold options..... I think the "only" easy way is to get a DIY turbo manifold kit and use the flang + 4 90 deg bends to start off the manifold and then make the rest up.
OK it will be in mild steel but hey its not the end of the world if you use good quality steel in the first place (plus the VX is nice and shielded from the world)
a Pacesetter manifold "might" be possible with some modding (ie bend it more) but the shorty manifold as shown in the first post cant be modded with ease.
