Default emissions whats the difference

hey whats up guys i was wondering why the guy at the import jdm motors told me i had to change the headers that came with it and the intake to pass emissions also would changing it give me less horsepower or is the guy just trippin on emissions does it let more fuel burn in the motor because they look exactly the same

just put on the US spec headers and stuff, and pass smog, then put on whatever you want. but i thikn that the JDM stuff doesnt have some sensors on the IM that you have to have. i need to get a USDM IM and ecu to pass my car. stupid BAR.
