130hp...55tq
sorry the header only got you 3hp to the wheels at most...dc sucks ass...might as well be stock frankly...any header taht is not a race header that deletes the cat is not goiong to yeild you much HP..heres a REAL dyno of a dc sports header not that bullshit manufactures claim http://www.hondahookup.com/info/99_02_si_dyno_results.php a dc sports 4-2-1 header on a 2002 civic si made 3hp.3-5 maybe on the intake, the header has to produce more than that. Those are low numbers?
