So i got a DC Sport 4-2-1 header for my 00' ex and installed it this weekend...stripped a bolt and halted everything for a day but it eventually went on, and i didnt have to use the o2 sensor extender, it just plugged in right where the stock one was. So anyway my question is when i acceleratei hear like a whirring sound of air, i dont know if its the air going through the new header, or the inake being affected. Anyone know what im talking about or have this happen or am i just goin crazy??
