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

 

where do you live? and what swap into what car?

 

i live in cali
and its a d15b
my d16z6 broke so i got this as a replacement

 

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.

 

kwl thanks


do u think the jdm exhaust manifold and intake manifold will give u more hp or the same output

 

not much, i know that the one on my jdm gsr is a little bigger than US, but its not enough to feel. just get an aftermarket header thats CARB legal.

 

kwl thanks

yeah my intake manifold is a little bit bigger to
