Alright i have got a 2003 civic si, and I just reached 10,000 miles on it. My mantenance required light is on because I have to go get the tune up it tells me to on the owner's manual. Well I knwo that the cai doesn't void the warranty neither does the exhaust. The thing is I have a header on my car and I think that voids my warranty. If I take it to go get that tune up and for them to check that everything is alright on my car, will they talk **** to me about the header or what?

you do not have to take it on at all. that lights comes on every 8k miles or so automatically. no one goes in for a tune up. all they will do is reset the light which you can do yourself.

Don't take it in unless something is wrong. The reset sequence is posted, if you change your oil regularly and replace/clean (if reusable) your air filter as directed, then all those lights are there for is so Honda can have more of your money. Those interval services are bullshit.
