how is a powerlog and ported rear mani within your budget, but headers, which can be found for a little over 200 bucks anymore, are somehow out of your price range?
Not to mention that a powerlog and ported manifold are worthless without a bigger downpipe, which right there puts the total price at MORE than some of the current headers out there.
Ported manifolds are a sham, and a complete waste of money, and with as cheap as headers are anymore, the powerlog is obsolete for anything but a turbo setup.
save a few more dollars, and get something worth your time, effort, and money.
