I spoke with George at Kooks Custom Headers today and they are willing to help with a set of headers for the SSR. I explained the need for a 1 7/8" primary and 3" collector setup for a true dual 3" system. They are located in the Bayshore area of Long Island and need a 05-06 SSR with LS2 to use for development. Please respond to this thread and I will give you the e-mail address. Thanks!
