emmissions w/ aftermarket header

[J.P.]

Whats up HAI,
it's time for tags on my 2000 civic si. I have a jdm 4-1 style header not carb exempt. Am I going to have a hard time getting it to pass emissions. I know the car can pass but I don't know if they need to see a label on it stating it's legal. I really don't want to tear apart my exhaust system over this.

jdm 4-1 header.
2.5" carsound cat.
apexi ws exhaust. so not loud and ricey or anything like that.


Thanks for any advise

I think you will be alright. I have DC 4-1 ITR style with the 2.5inch collector, random tech cat and greddy cat back and I passed.

[J.P.]

Thanks for that info. did they even mention anything.

CARB is California crap only. They don't give a shit here. It should pass.

You'll be fine. CARB is California-only. As long as you have a functioning cat & muffler, and the car is tuned, you should be good to go.

you can go in with a fully built motor and be boosted they won't say a thing may stare at your motor...basicaly they look for cats and o2 as long as you have the them then your good.

yeah only problem i had was they made me go back and change my rims. they wouldnt do mine with aftermarket rims. then all they did was check for cat & pressure check the gas tank. didnt even look under my hood.

They checked under my hood, and I got compliments from 2 of the guys there.

I passed visual with a turbo on my Storm. I also passed the sniffer easily. A header won't do anything to emissions as long as you have a cat.

Hahahha yeah you should be fine. You should start worrying when you have a turbo, big ass injectors, big fuel pump, no cat, etc. :D

why did they make you go home and take off your rims, sounds kinda gay

My husband had to do the same thing with his sol. He has low profile tires and when they run the tests the tires/wheels run the risk of rubbing and being damaged badly.

[HuNgiEbOi]

they do that because there are restriant that come from the side of each wheel and there is a possibility of it rubbing on the wheel if you guy have rubber band as tires. This only applies to front and all wheel drive because they move side to side.
