Ok...now that we have had a bunch of header questions already today, I will add another. I was driving up around DC and Baltimore this weekend on the interstate and due to the ungodly roads there, my exhaust took a beating. Needless to say, it gave me a reason to replace my system. I want to replace the manifolds with headers. Based on the threads I have read here, it seems to help the engine breath a little better. My question is what happens with all the emmission stuff like the AIR pump and the rest of the stuff connected to the stock exhaust manifolds? I know they have to come off. I'm not worried about the emmissions aspect...we dont have to have it tested yet here in VA Beach.
