4 branch manifolds

[Gabbo]

been looking to buy a 4 branch manifold for my 2.0ltr 8v and seen that there are 2 types, a 4 into 1 manifold and a 4 - 2 - 1 manifold.

are there any differences with them in power wise or noise wise or just the exhausts them selfs??

cheers :)

ive not got solid evidence on this, but ive been told from a fairly reliable source, depending on what the main purpose of the car will be used for, 4 - 1 will give the highest flow, so good for track cars nailing high revs all the time. 4 - 2 - 1 gives slightly more back pressure, so good for road cars that use lower revs. again from what ive been told, id say if your tracking it, or your just hardcore... 4 - 1 it, but if its a standalone road car u wont go wrong with the 4 - 2 - 1 design.
