Why not get it stepped and a custom TD setup to fit?

well that's what i was going to do...in fact, im going cutoms TD anyway, but the stepped headers are much more expensive and if i'm not going to see any gain, they're really not worth it.

besides, i'm going to be selling them in a couple years anyway when i get ym turbos and i think the standard 17/8" will be easier to off load for closer to what i paid for them
