I been wanting to get some headers for my Xb but i cant figure out what to get. I heard that some of these unknown brands manufacture some good headers. The thing is they are going out the door at 65 bucks a pop sounds a liitle weird. Does any one know if they is a difference between these and Greddy and DC sports. Need some feed back ASAP[/img]

 

You don't say what state your are in, but since you posted in the Pacific South I assume California. If that is the case you need to get a CARB approved header. I know DC makes one, but not sure of others.

 

Can any one tell me what brand of headers make carb approved for the state of california. And maybe how to know if they are carb approved or not. If i did put some not carbed approved would it affect my smog test in any way.

 

You are looking for a statement that the header is CARB approved and/or 50 state legal. The manufacturer needs to supply you with a sticker to certify legality. You would possibly fail a visual inspection if you did not have the certification. Here is a link to the DC model.
