how good would you say ractive headers are? how do they compare to DC and GReddy? are they CA leagal?

You get what you pay for.

I bought a Ractive SS Header and it was terrible qaulity, it didn't fit right and it leaked. I exchanged it 3 times and finaly got the DC Sports and it fits right and does not leak. Howver I didn't really notice any significant hp change between the two. My friend has a Ractive header on his 94 Gsr and it fits fne so I don't know what to tell you but that to just go with the Dc Sports.:D I have heard the the JG Edelbrock header is good also.

I have a Airmass Pro-Racing header, it was alittle cheaper then DC... bolted right on, took me about 30 minutes to install, i noticed a some increase in power, makes my engine compartment look real nice.
