Surprisingly, there are no (if not, few) headers for your car/engine combo. I'd say, save up some extra money and get a better engine. Then you can throw a header on there and get a better engine to boot. Another option is a custom made header, which isn't cheap either.
go for the HP header made for an ex. the header basically bolts right up and all you have to do is find a o2 sensor to plug up the second primary. i believe i saw an artice in import tuner where they did this with no problem, and if you can find Nexus242 on the board, you can ask him how he did it to his DX. the HP header is a bang for the buck mod somewhere around 200.00 for the chrome plated one. hope this helps.
