can any1 tell me....wat are the best exhaust, intake, and headers for a 2003 nissan maxima??

 

First, welcome to the org.

That's a 'loaded' question, as there are many different opinions as to what is 'best'. As a new member, I suggest you look through the FAQ's and scroll through some of the pages in this forum to research the items you have mentioned, as these topics come up very frequently. There are many threads that will give you a lot of good info. It will take you some time to do the research, but after you do, you'll be able to post more specific questions.

 

Best of luck. I'm sure about every part made will be mentioned here and everything will be called the "best" by at least one person. Best this is to do what Bluesbrkr says above.
