GReddy intake manifold all the way. none of the knock offs for rb25's flow to cylinder 6 correctly, my friend has a hole the size of a quarter in his 6 piston. flow is the major issue and 99% of no name brand intake manifolds you'll see have never REALLY been flow tested. if flow wasn't important to you, you'd be running the stock intake manifold. so why not get what you're looking for? tested, proven, reliable, it's DEFINATELY worth the price. exhaust manifolds are a whooole nother story, i've been running an xs power top mount and haven't had a problem with it.
