For all 992 GT3 and 992 GT3 owners drivers worldwide this is a complete 992 GT3 long tube headers to tips exhaust solution for ultimate weight savings and performance. The Fabspeed RennKraft® system  features our U.S. patented RENNKRAFT® system- this allows Catted and NO cat systems in a modular PATENTED design.  Designed and guaranteed to be the most powerful emissions compliant exhaust system possible. We used all 25+ years of Porsche exhaust design experience and our finest manufacturing techniques to engineer this incredible modular system. Fabspeed Motorsport engineering started with the headers. From our experience designing our 991/991.2 GT3 Long Tube Headers, We knew that “long tube” headers were essential for making BIG power on the GT3 platform. After dozens of dyno runs and many revisions to runner length, diameter, and  pyramidal F1 Indycar merge collector design we moved on to CAD designing the catalytic converters and rear section. With perfectly optimized headers and EMITEC HJS German imported high-flow racing catalytic converters, there was no room to fit the factory muffler section, so that went out the window. In its place we implemented extra large 200 cell HJS cats and our signature investment cast CAD designed  70mm 2.75" X-pipe. These cats flow so much better than stock, that we only gained 1-2 peak WHP when we tested the system with no cats. You can see the dyno graph for yourself above. Finally, after much testing we found that our cast X-pipe provided some significant gains from 3-6K RPM when compared to a simple crossover tube or 2 separate "easy lazy to make" 90 degree pipes. With the patented RENNKRAFT® system, you can easily swap between catted and cat bypass using the quick release v-band clamps (patent pending). So if you’re going to the track for Endurance Racing you can swap in cat-bypass pipes for endurance Racing Competition events. BUT you can rest assured with Emitec HJS German European certified Homolgated racing catalytic converters you are leaving no extra power on the table while making maximum Clean and Green Performance. tm. 

SOUND:

This system is awesome as its the lightest weight emissions complaint systems that could be factory installed on any Porsche RSR GTLM GT3R factory race car. it’ll turn your GT3 into a snarling aggressive race-bred machine. This system is LOUD, it pops and gurgles, and it will absolutely scream to redline. This is at the cost of some interior drone and day-to-day livability. We have many people Wolrdwide that love this system and like the massive weight savings versus stock and OFF the rear end for better handling. This systems is 100% manufactured at Fabspeed Motorsport USA. 

 

 

POWER:

This is the way; the most powerful emissions compliant 992 GT3 exhaust system on the market. Max gains of +35 HP and 39 ft/lbs of TQ are seen at 4250 RPM. Usable power ALL across the RPM band from Fabspeed Motorsport applying over 30 years of Air-cooled and water-cooled experience.  You’re going to feel the power that this system adds to your GT3!

FEATURES:

• Fits all Porsche 992 GT3, GT3 RS Models Worldwide (This system does delete the GPF on EU cars, and will cause a check engine light for a monitored GPF system unless a simulator or tune is used)
• Adds 35 HP and 39 ft/lbs of TQ at 4250 RPM
• Saves a massive 18lbs / 8.2 KGs versus the stock factory Porsche OEM system
• Equal length headers with Burns Stainless Formula 1/ Indy car style high velocity merge collectors
• 100% mandrel bent in-house and manufactured and QUALITY controlled at Fabspeed USA. 
• Springs used for collector retention to accommodate for expansion and increase durability
• Constructed from T321 stainless steel Mil Spec tubing- ASME specifications
• CNC mandrel bent tubing featuring 2.75in / 70mm tubing
•  CAD designed investment cast stainless steel flanges for maximum flow and strength
• Modular design that uses a V-band clamp so one can quickly swap between cats and cat bypass
• The RENNKRAFT® system has been awarded a US Patent and is the only system of its kind in the world
• Switching to cat-bypass for track events prevents catalytic converter degradation during all out Endurance Racing competition racing abuse
• We use German-made Emitec Tier 1 HJS HD tri-metallic 200-cell EURO 6 homologated catalytic converters for the best performance and reliability
• Optimized for maximum performance with NO catalyst generated check engine light, guaranteed, when Sport Cats are installed
• Comes with your choice of exhaust tips: Matte carbon fiber, mirror polished stainless steel, brushed stainless steel, Satin Black and 90 degree race turn down tips for sound control
• Simple bolt-on installation, no cutting or welding required
• Incrementally DYNO developed and tested versus other brands that often BUILD something/ anything and simply GOTO market with hype. Caveat Emptor.
