Fabspeed's 991 Carrera Performance Package includes the following upgrades:
Maxflo Performance Side Mufflers w/ Deluxe Quad-Style Tips
The 991 Carrera Maxflo Performance Side Exhaust replaces the factory side mufflers, improving the exhaust flow and the overall power while providing a deap and throaty sports car sound. This system can be used with the OEM outlet tips, or can be upgraded to include Deluxe Quad-Style Tips in either Black Chrome or Polished finish.
Sport Headers w/ 200-cell HJS Sport Catalytic Converters
Performance headers improve exhaust flow and sports car sound by improving the geometry and replacing the restrictive factory catalysts with high-flowing 200-cell HJS Sport Catalytic Converters.
Center Muffler Bypass X-Pipe
Improves exhaust tone and saves weight by replacing the factory center muffler with a lightweight x-pipe.
Carbon Fiber Competition Intake System
Improves cold air induction into the engine and improves power and sound through the rev range; constructed with genuine carbon fiber for strength and durability.

Depending on the rate they charge at your local shop, we recommend about 10 hours. As far as the gains, we have not had the opportunity to dyno this particular car with the full package all together.
Although they can not simply be added all together like we all wish the products that make up this package show great gains.
Maxflo Mufflers = +15hp and +11ft/lbs
Sport Headers = +23hp and +22ft/lbs
Center Muffler Bypass X-Pipe = +16hp and +14ft/lbs
Carbon Fiber Competition Air Intake = +9hp and +12 ft/lbs
