Exhaust manifolds, MC1/MC2/KH/UR-Q

[Michael Gough]

Hello list,
I followed the manifold discussion a wile back, but I didn't notice any
mention of this. Are the MC1 KH and ur-q exhaust manifolds all relatively
the same? I know the MC2 is the 2 piece, but is there any difference between
the ur-q manifolds, the KH manifolds and the MC1 manifolds? Just wondering
if all of the 10v exhaust manifolds flow about the same.
Thanks a lot
Mike
