Porsche 997.1 & 997.2 GT3 Exhaust Headers
Performance - Perfection Redefined.
The Porsche 997 GT3/RS is one of the greatest modern day supercars on the road and racetrack. The tried and true Flat-6 power plant has proven itself as a bulletproof platform for modern day endurance race cars. Ardent's headers are designed to maximize the potential of the GT3 engine while significant increasing power using superior hardware and more precise engine software calibration.
Unsurpassed Quality, Fitment, Performance and Sound... Made in Arizona.
When we set out to build the finest header system for the Porsche 997 GT3 models, we had a monumental task in order to create something better than what Porsche developed. We determined the shortcomings of the OEM system and made significant improvements to the exhaust flow characteristics. Our design helps equalize each cylinder's exhaust pulses for better exhaust scavenging and consistent exhaust temperatures. Additionally, we paid close attention to the exhaust flow into the catalyst which has recently become a problem with the OEM headers. The flow of the factory exhaust manifolds into the catalyst has caused excessive heat which causes this premature catalyst failure and cracking of the factory header before the catalyst. These issues have been corrected in our header design which helps reduce exhaust restriction and temperatures for increased overall power while improving the header integrity.
Designed to be Versatile.
Our modular design allows you to switch between 200cpsi high-flow HJS catalytic converters and test-pipes in a matter of minutes. With V-Band flanges, the swap can take place during your normal track-prep prior to a weekend of turning fuel into exhaust and rubber into smoke.
