    Generally, from what I can remember, the EP3 and the base RSX are direct swaps. Since its a type S, you may need some modifications or other type S piping.

    If I remember correctly it will fit but the rsx specific header is longer than the ep3 and you will need a rsx specific mid pipe to make it fit. Not sure bout clearance issues with the sway bar.

    you are going to need a DC5 midpipe if you are going to keep your ep3 spec exhaust.

    Alright first off its a header, not headers. A Type s header will be abit longer than the ep3 header, so you either need to run a type s midpipe or cut some inches off your ep3 midpipe. You shouldn't have any clearance issues.

    They all hit the nail on the head. Your mid pipe will just have to be cut some 3" shorter, or you'll have to source an rsx-s spec mid-pipe.

    Easy as that.
