Can someone help a noob pick headers

kfcgodsword

So the last bolt on I want to install would be some new headers, and possibly with some test pipes or HFC's if I go short tubes. But trying to figure out which ones people like, or if they are even worth doing at all, is a little daunting.

So far I have the Z1 CAI and Invidia Gemini CBE installed, and I am really enjoying the car. The headers were the last thing I wanted to add on before I get a tune. My main goal is performance, but without becoming super loud (hence the Gemini)

I've heard that long tube headers are the move if performance is the main goal, but then I begin to worry about the sound. The Z1 400hp package has also caught my eye, but those come with short tube headers and either test pipes or their HFCs. If you were in my position, and wanted the best performance possible, but as little noise gain as possible, what would you do?

Would love to hear any recommendations or suggestions. Bonus points if you know a good shop in the Portland OR/Vancouver WA area to take my Z for installation.
