Well I just scored BIG TIME and bought a Genuine DC Sports 2pc 4-2-1 Header for my 2000 Civic EX from a guy on Craigslist for $35.I know its real because when I picked it up it had the C.A.R.B. plate welded on and pn# HHC5013 stamped on both upper and lower halves. This thing is brand new and only has a couple of scratches outside from being moved around his shop. The only thing it did not come with was gaskets or bolts. Now the only question I have is, can or should I reuse the OEM gaskets that are on right now or should I go and buy new ones for my whole system. I am looking for the head gasket, O-Rings, bolts, the gaskets before and after the catalytic converter and might as well replace the ones on my DC Sports Cat back exhaust. Where is a good place to buy these? Thanks!
