Lookin to buy a header... need some help

[Sivik]

Hey guys,

I'm about to buy a header for me 98 EX. I'm curious to which kind and brand offers the best gain for my car, and I do plan on turbo'in it later if that has anything to do with it. Couple questions first:

1) Best brand and quality?
2) 4-2-1 2 Piece, 4-1 2 Piece, 4-1 One Piece?
3) How long does the polished look last?

Matching header to a Tanabe Super Racing Medallion.

Thanks!
