I've got an AEM short ram and I love it, and my WS II is on a UPS truck right now. The DC header is also supposed to be second only to comptech and high priced headers like toda. I'd propably have that ordered too if I wasn't considering boost. As for stainless or ceramic for your header, I've heard a few people who perfer ceramic, but it's obvious that most like the SS for not only looks, but durability. The DC ceramic header is made with mild steel and then the ceramic coating, but I've heard that may start flaking off after a year and you'll want to recoat it before it rusts. Also, I've heard of a few hairlines and stuff in the ceramic. As a general rule of thumb, the more you pay the better that part will be. Companies like DC and AEM do R&D before putting their products out. Other companies just try to copy them. Plus, you'll notice the welds and parts get alot better with price. I've heard some horror stories about the obx headers. Anyway, good luck on your choice.
