what exactly are you talking about? their is almost the same things out for the S14 as the S13. i know heavy throttle fabricates a hot pipe for the S14 i am not sure about enjuku though, at any rate, you can just get a S14 intercooler for your car any just have the hot pipe made for you. it is not that long of a piece, any you can use all the other pipes that come with the i/c.
