I was just looking up pipes and there is much of a selection for 350x and i seen that 400ex has the twin header to, so i was just wondering if anyone has tryed it or if anyone knows for sure that it will fit, becasue there is a ton of pipes and jet kits for 400 ex, i assume the carbs are almost identical and might take the same jets, if someone could give me some input on that and let me know if my crazy ideas would work?

basically. yes. The mid pipe on the 400ex takes some modification, depending on what silencer you're using. when I did the conversion on my brother's 350x, I had to drill the flange bolt holes a size or two larger on the ex exhaust. A lot of people have put 400ex carbs on their 350x's. I hear it makes them start a lot easier.
