im not sure if its true or not, but my friend told me that headers are illegal here in so cal, and im not sure if it is because ppl say its good for a small hp gain to ur car. so is it or is it not illegal?

 

The faq has some information about it but basicly it has to be CARB leagal....(california air resorce board) which means it has to be certified...DC sports has carb legal headers and i think megan racing has a few..just make sure its carb legal and your good to go.

 

some companies makes California legal headers, including DC. Expect to pay $340+ for them though, but thats the price to keep it legal in Cali. Not all DC headers are Cali legal though, so make sure it says it.

 

Yes it has to be DC Sports carb legal. Here look at my newly installed headers. I also live in southern Cali 951. https://www.hondacivicforum.com/m_539923/tm.htm

They sell dc sport headers at a Honda dealer in Diamond bar..Give them a call 909-594-6632 I believe there headers run about 280 with shipping included.

hey civic si 00 is it possible that they sell headers for 06 civics?? and another question i have is that if it says civic si 06 would it still fit in a normal 2006 civic ex

 

I don't think they will fit ..2 totally different engines..Give them a call tomorrow they should be able to answer you bro..
