I was curious. I have to go with the NHP headers because I have a Tiptronic trans. They have a set with 200 cell cats and will not trigger a CEL and no modifications needed to work with a Tip trans.

I am going with secondary cat delete pipes from Circuit Werks. You've raced your Boxster at Laguna Seca?
