I've posted this link a time or two before, but I don't think anyone noticed. Ahnendorp in Germanyhttp://www.ahnendorp.com/ has a stainless header for the waterboxer that is true equal length. The collector is under the center of the rear bumper just like the air-cooled headers. The website is in english, they post currency exchange rates, and have instructions for shipping to the US. The possible problem is that US emission regs. say that the catalyst has to remain in it's original location. With this header it doesn't. I can handle that issue and plan to order one of these things later this spring.
