I bought another charge pipe with a meth bung so i'm selling the one i used from Ultimate Racing. It has an HKS flange so you would only buy it if you plan to use an HKS Blow Off Valve (which are the best IMHO). I will not sell my HKS BOV with it as i am going to keep it. It sells for $250 but i will sell it for pretty cheap. Here is a pic from their website:
