Cali-spec manifold for california dudes, or proven race cars wishing to fly beneath the radar.

Something else about these manifolds in general, anyone looking to step up to a 'big power' manifold is also forced to look at upgrading to a 3" TB and with them come reliability concerns and driveability issues.
Furthermore, there have been quality control issues with the Driven Innovations SMIM on multiple occasions with welds breaking, runners cracking, and worst of all fuel rail mounts breaking off. These issues combined with the stock-like driveability (uses ported stock TB) make these manifolds *the* manifold of choice for top-end users.
For those that don't know, Wilson Manifolds has been in biz for *30* years making top-quality products, and this is no different. Def a name you can trust, if you're willing to pay for it.
Also, no word on the v0 manifolds yet, but real world it is probably going to perform similar to the standard ported manifold (I paid $75+core for mine), so for the $550 or w/e they're talking about charging, probably not worth the dough.
