below is a link from evolutionm and i was wondering would those headers fit the 04-06 ES as well. just wondering because i keep seeing headers with different shapes. one goes straight down(rrm header) and the other one curves at the end(ebay/other headers) and im not sure if both are applicable or jus one type because they all say there will fit 4g94's So which one will fit 04-06 ES? http://forums.evolutionm.net/lancer-how-requests-questions-tips/492387-ebay-headers.html
It will work the exact same man. The one I got that I posted on there will work on your car. Any 02-06 lancer 4g94 header will work for your car.
I'm pretty sure that David is correct. As long as it says that it's for a 4g94, I don't see any reason for it not to work with your car.
