I bought this off E-bay to port for use on my non-SAI Cobalt LS.
The problem is, the guy never told me it was for an SAI model.

No one wants a stock one, so I ported it.

Since they do not offer anything for the SAIs thus far with headers, this is like buying a GMPP manifold for a non-SAI

$70+ shipping

Will provide before and after pics if serious in buying.
