Default Exhaust manifolds - which one?

OK, i'm confused(again!) I see ads for 2wd saphs where its states that a 4x4 manifold has been fitted and then I see other ads for 4be's with 2wd manifolds fitted. Does this mean a 2wd runs better of a 4x4 manifold and therefore a 4be goes better on a 2wd one or is this a load of bo**cks????

it all depends on the power output you're after, i have a 2wd and i put a 4b manifold on as it allows the turbo to spin up slightly faster as it has a smaller internal volume compared to the 2wd version, but if you are going for over 400bhp you would be better off with the 2wd manifold as it flows better and produces better torque curve and as said better flow at top end.
Hope this helps
