Thank you everyone for the informative and helpful responses!
@Jim: The info on gaining performance is very interesting. I hear you the emissions in Califoania. I was looking for some street legal headers with the A.I.R. tubes and a C.A.R.B. certification for my truck. It seems like only two companies make them and charge a pretty penny.
@Boothboy: So that's
why the smog requirements are so strict in California! Lol!
@LATECH: That is pretty clever. I've never seen it on any of the newer cars I've owned or driven.
