This might be a stupid question to some but im just curiouse. when time comes will exhaust and headers affect the chances for the car to pass smog control. im from california and we have some strict smog control laws here. thats why im curiouse.

 

you can have any exhaust I think, as long as you have a cat and it's not loud, and header too, as long as you have a cat and your o2 sensors you're good. Pretty much as long as your emmissions stuff iis their and pass the visual test y'know.

 

i dont want to sound like an a-hole but if someone know for sure i really wanna know

 

Like I said, above ^^^^. I live in California too, and I passed smog, cops never harass me either.
