This is my 2000 Civic Si not much on performance but more on look.lol. Hey does anyone know what is the best Air Intake, Intake Manifold, Headers, Cat, and Catback Exhaust for the 2000 Si. I think that JDM Password Carbon Fiber Air intake is the best intake because of the size of the intake being so big so more air is going in when compare to regular air intake with a 3" piping. Thanks in advance.
