If you really want to go all out, go with a JDM ITR Header. More power than any DC header and it looks sick.

Since you are looking for cheap, go with a DC sports 4-2-1 or 4-1. The ceramic isn't bad but doesn't last for as long as a stainless steel one.

Don't go cheap because the welds will crack considering the header is one of the hottest parts under your hood.
