FabSpeed Porsche 996 Carrera Performance Package (1999-2004)



Why We Choose HJS Catalytic Converters: 

HJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light.

Includes Maxflo Performance catback mufflers, HJS German 200CPSI Sportcat X-Pipe, Equal length performance Headers, Competition Intake / Cold Air upgrade kit (Year Specific), Fabspeed ECU Tune & Deluxe Quad-Style Tips.   Over 24 years of continual development refinement resulst in the World's very best system for the 996 community.                           

Fabspeed's 996 Carrera Performance Package replaces the restrictive OEM mufflers and factory cats with high-performance mufflers and 200-cell HJS Sportcats for a deeper, throatier exhaust note and improved power and throttle response.  The included Performance Headers replace the restrictive factory headers and with high-flowing motorsport headers.  Lastly, the restrictive factory airbox is replaced by Fabspeed's Carbon Fiber Competition Intake System for the 2000-2004 models or the Cold Air upgrade kit for the 1998-1999 models which increases the cold air flow into the engine for better power and sound.  All of these upgrades are then optimized by the Fabspeed ECU Tune which re-maps the timing, air-fuel ratios, and more in order to take full advantage of the upgraded components.
