Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I have a 2003 996 and was thinking of doing some performance enhancements. It looks like headers come stock on the 996 and I was curious if there is any real difference between the stock Porsche headers and upgraded headers. Are upgraded headers lighter and more polished inside than standard Porsche 996 headers??
The general consensus has been they don't offer much in the way of performance. I've heard many say the underdrive pulley was the best bang for the buck (by far).
