I thought it was some kind of super secret HAN handshake code that I wasn't allowed to understand quite yet.

HyTech and SMSP both have a lot going for them, and many of us can point to significant dyno gains with each of their headers. Hell, I'm using the old SMSP design and I'm still delighted.

If you don't have $1000-$1400 to spend on a header, though, I still think either the DC JDM 4-1 or the Honda OEM 4-1 headers are awesome. Mate this cheap header w/a cheap 2.5" custom exhaust, and you've got a very decent gain for a very little amount of money.

Aficionados are going to want to aim a little higher up, though, because few of them are satisifed and they'll keep trying to improve their cars. If you're one of these folks, you're better off saving up for the SMSP, because the cheap headers will not be able to keep up w/your modifications.
