Also if you have a turbo the size of frankensteins head you need a 2wd manifold other wise turbo won't fit, it will foul the side of the head

2wd manifold comes in 2 pieces, the main body of the manifold and the 'swan neck' the bolts that hold the two pieces together can be a pain in the arse to source too has a better top end flow rate as said its adviseable to use a turbo damper, takes the pressure of the manifold studs again especially if you have a big turbo

4x4 manifold is a single piece unit
