Beautiful looking headers. Ive heard that performance enhancement varies significantly between the different manufacturers headers/collectors systems. Any noticeable (or dyno demonstrated) improvement?

They sound a little throater. On the dyno, they accounted for an additional 31 hp. The car was dyno'ed stock and then with headers only add. I can post the dyno sometime today.

Mark at * *** ** Racing built them. Mark has been with them for years and prior to that he was with Sanderson Headers. He really knows his headers and he is a fanatic when it comes to quality and design so as to extract the most power available.

I doubt they would fit as the GT3 heads are different than the 997S. However, they build headers for all types of Porsche's.

Yes the car is stock. No, the CEL was NOT triggered. The are kat bypass headers.
