Anyone know the Tech Spec of the GTSpec Manifold?
 

Anyone know anything about this Manifold/Up-pipe Combo - good/Bad Reports?

Anyone know the Diameter of the piping - i.e. 54/58/60mm?

Its £425 all in and is a 3 bolt flange design on the up-pipe..............

I presume its an unequal length jobbie for Performance?

I have a set of these and the quality is fantastic. They are un-equal, I don't know what the diameter of the pipework is. Before these I had a set of Tony Law equal length headers, and I noticed no performace difference whatsoever between them, so they are obviously on a par with other performance headers.

I'm just waiting for some to come in from the States...........
