I dont get it ive been looking and keep seeing different ones i know they are aftermarket ones also which i am thinking about getting and then getting it powder coated to cover any pinholes but still want to buy the Greddy also just to be safe

But look, does anyone know the differences?

the cheap one you found are probaby the chinese knockoff w/ poor quality casting--use at your own risk, don't come back and b1tching about it.

Powdercoating a chinese manifold is akin to polishing a turd. Nice turd.

The first two are the same.the third is basicly the manifold less the runners. you will need to cut the factory runners off the factory manifold and tig them to the greddy manifold. Is basicly the cheaper way of doing it. X2O and other knockoffs are crap... I love my Greddy!

umm the third is most definately for the rb26 and not the 25. Remember the the 26 has independent throttle bodies. No welding is required on the third.
