I was referred here by another member... We are interested in building headers for the crossfire & the SRT6. If we can get a car to use for the prototyping, the owner of the donated car will receive a production set at pure cost! If we can organize a group of people that are interested, the price would be even lower. We are a custom header manufacturer, and currently offer shorty headers for the E55 Kompressor. We have an SLK32 coming in for the same type of situation, along with a SLK63. While the SLK32 engine is similar, there are differences, so a new header design is warranted. You can view pics at: www.flooredfab.com. We are always looking to help out in anyway we can!
