I've got an oppurtunity to buy a used Hulkspeed front ported exhaust manifold for about 50$. It has 25k miles on it.
From my research it seems that the zzp powerlog is worth the extra money. Because there really isnt much you can port anyway. The zzp powerlog is like $220 shipped also, which is crazy (but more power to them).
What do you guys think?
