williams manifold

[chris16v]

Can you put a williams manifold inplace of a valver manifold? doing this replacement do you loose any power?

[MattyH16valver]

The manifold would fit, but you would have to get a willy cat or a de-cat/adjustable de-cat as the flange on the manifold is a t a different angle to the valver one.

[drsmith1979]

you would lose low end torque, but have increased top end. not sure on the downpipes, think they are different too...

[Allan]

It all lines up fine, if you use a williams manifold and williams down pipe, but the front flange on the cat is 45 degrees out compaired to the valver cat, so you cant mate them up... but just get a willy cat or decat and it would fit fine.

cheers for every ones help with that!
