Shark Werks Bypass Exhaust for 997.2
The new SharkWerks 997S muffler bypass system has been methodically designed, tested and proven on our own 2009 997S PDK car during the first few months of ownership. Whilst we were excited to own and drive the new generation of 997 one of the areas we felt needed more attention was the exhaust note. In stock form the sound was extremely quiet inside and out. The goal with our center exhaust replacement was to achieve a PSE-like sporty Porsche sound that we all know and love and yet retain factory fitment and be 50-state emissions legal.
** This system will only fit 2009 / 2010 / 2011 / 2012 and newer Carrera / Carrera S models. It is also compatible with the PSE (Porsche Sport Exhaust) equipped cars and continues to work with the sport button.
Designed in-house and manufactured in Northern California the muffler bypass utilizes high-grade 18 gauge T304 tungsten inert gas welded stainless steel. The center replacement improves upon the factory unit by eliminating the sharp and tight left/right u-bends in favor of a straighter flow for a real world 12HP and 14TQ gain (see dyno plot below). Retaining the side mufflers maintains an appropriate sound level for daily driving (especially in a PDK car which is subject to droning). There is no additional drone or resonance. Should you ever want an even more aggressive sound you can also combine our bypass with aftermarket mufflers designed for the factory center section (e.g. Cargraphic).
