Far as I can tell its cheaper than the m370, you gain "almost" as much mid range as the m370, yet you keep your top end as if you kept the stock mani. All in all seems worth it. I think though $300 is a little to much. A local shop or you could knock this out with a drill and the right bits/sand paper bits.

Can you explain both of these statements??? Between 4500-5k RPMs, where the M370 is known for its low end tq gains, the Z1 manifold is clearly almost 10whp AND ft/lbs of TQ lower!!???

Its all going to come down to opinions of "which is better" because different people have different wants out of the manifold(top end whp, or lowend midrange TQ). The Z1 Manifold has some clear gains up top over the M370, but are those truly "gains" when comparing to the M370, or just avoiding losing top end AND losing low end vs the M370.

The Z1 needs to be compared vs the OEM manifold, not the M370 to get true gains vs OEM.
