+1 on eBay. But if I had to do it again I wouldn't have put a header on it. At least not an obx. Mine didn't fit right and had to do a lot of grinding so it would not hit the oil pan and the stainless is way too thin. Also I didn't like the loss of torque down low. I just though it was more a pain than with. It does look nice (for a month or two and is a lot lighter than stock) but My sri aem gave me the most gains.
