does anyone know how many Hp a DC header givs?

the car is an -93 2,2 vtec

i also has a CAI,exhaust 2,5.

need to know if itīs worth to buy.

 

i would recommend that you get a prospeed or at least a greddy, do a search and you'll find all the info you need. I got a DC and its not terrible but not that good either. Im taking it to a local shop to get the collector upped to 2.5 in and a high flow cat.
