Can you please forward me this info. every tuner that I have talked to (American and European) thinks that these headers are not worth anytthing and there is a gain there.
I have one thing to ask though lets not discuss this if you are not a believer of aftermarket improvements. I do not think that what Porsche builds is perfect since they have to think from marketing perspective, comply different emissions and etc. I believe that it can be improved and once you are believer of one side it is pretty much a dead discussion.

The 997S headers (shown at the bottom of the attached picture) sure look more restrictive than the x51 headers.

These look like the stock 997 S headers. The X51 headers are shown in the above picture by avantgarde and look alot like the Fabspeed headers.

What about Tubi? They don't make exagerated claims like the others. Even my dealer says that there is some power gain, but definetely no more than 20hp.
