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. Fabspeed 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.

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 +37 HP/ 31 WHP (whp= horsepower at the wheels) and 39 ft/lbs of TQ are seen at 4250 RPM. That's 357HP at the crank! Gains of over 20 WHP are carried all the way from 6000 RPM up to redline. Usuable 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!

Who is FabSpeed?

Fabspeed is an aftermarket company that has been in the automotive industry for more than 25 years. They specialize in creating high-quality and high-performance parts for various vehicles. They provide parts for some of the industry’s hottest exotic cars. Today, they have created a name for themselves and are steadily growing and extending their reach in different parts of the world.

The company offers a wide range of products ranging from performance air intakes, exhaust systems, and ECU tuning. All of their products are created in the US and are handcrafted in Fort Washington, Pennsylvania. This helps them ensure that they create top-notched products consistently.

Their parts are made 100% in-house starting from design, engineering, manufacturing, and product testing. The company has a 26,000 sq. ft facility which oftentimes hosts events for car clubs such as Porsche Club of America, Mclaren, Lamborghini, and Ferrari. This relationship between their customers has helped them gain their trust making them the most sought-after brand for these exclusive market vehicles.

For over two decades, FabSpeed has been designing and building exhaust systems, ECU tuning, and air intake systems for exotic cars all over the world. Like many aftermarket automotive companies, FabSpeed is comprised of enthusiasts with a desire to help others go fast. Their talented team of engineers and machinists, plus innovative machinery, allow them to build products you can be proud to have on your car.

The story of FabSpeed starts in 1986, when a man by the name of Joe Fabiani purchased a 1985 Porsche 911 Carrera and got into his local Auto-X scene. Later down the line, Joe got involved in high performance driving events. When he built his first dedicated track car, a 993 Carrera, he couldn’t find an exhaust system that satisfied him, so he built his own exhaust. Word quickly spread amongst the Porsche enthusiasts at the track and everyone wanted the exhaust Joe built for his 993, marking the start of FabSpeed. FabSpeed quickly became a name synonymous with performance Porsche exhausts, but it didn’t stop there. By the mid-2000s, FabSpeed was developing and selling exhaust systems for many exotic cars ranging from Ferrari to Lamborghini.

The Best Vehicles Deserve the Best Parts

Fabspeed aims to create the finest performance parts to help enthusiasts enjoy their vehicle better. Their products are designed and engineered to further improve what is already a good performing car. Using real-world experiences and client feedback, they are able to develop their parts that would meet their client’s expectations. 

Why Choose FabSpeed?

FabSpeed Porsche exhaust compared to OEM porsche exhaust

You might think “there are tons of aftermarket companies out there, why should I choose FabSpeed?” There are many aftermarket companies who claim to be experts in exotic tuning, however, many of these companies don’t have the decades of experience that FabSpeed has. When you order a FabSpeed product, you know you aren’t just paying for a brand name. You’re paying for a product which is backed by talented machinists, welders, designer, and decades of experience.

Build Quality

It doesn’t matter how well an exhaust is designed if it’s built from low quality metals with bad welds. FabSpeed specifically uses high end metals and TIG welds their systems throughout to ensure the best build quality possible. No one wants to put a low-quality product on their exotic car, and you don’t have to with FabSpeed!

Design

As you can probably tell from the image above, automakers build their exhaust systems to a cost. Even on many high-end exotic cars, the OEM exhaust system uses a bulky design and super cheap materials. By designing the exhaust system with the purpose of increasing power and reducing weight, FabSpeed exhausts look and perform much better.

Performance

It’s no secret aftermarket exhaust systems increase power. With increased flow comes an increase in power. On top of the increase in flow, the use of premium materials and better designs also means FabSpeed exhaust systems weigh significantly less than an OEM exhaust. For turbocharged vehicles, the power gains can put the vehicle in a different league of performance.

Sound

One of best parts of owning an exotic car is the awesome exhaust note they produce. Because of government regulations, many auto manufacturers can’t make their vehicles as loud as they would like. This is one of the many reasons anyone installs an aftermarket exhaust. FabSpeed’s exhaust systems offer a deep, powerful, unique, and loud note that far surpasses any OEM exhaust system.

How an Aftermarket Exhaust Increases Performance

You’ve probably heard everyone on the internet tell you that aftermarket exhaust systems increase the power output of your vehicle, but no one every explains how the power gain occurs. Exhaust is a byproduct of combustion. There are three important things that determine how your exhaust gases flow through the exhaust system: flow, heat, and scavenging.

Total exhaust flow is determined by the diameter of the exhaust piping and the path of the piping. If you have small piping, flow is heavily restricted. If you have an exhaust with a massive amount of bends and diameter changes, it will also restrict flow. Scavenging occurs when the low pressure zone behind an exhaust pulse helps pull along the next exhaust pulse.

Heat is also a key factor to an exhaust system, however, its importance is amplified in a turbocharged application. As exhaust has cools down, the velocity it moves at decreases. For a turbocharged vehicle, high exhaust velocity means quicker turbocharger spool and increased boost pressure.

A good exhaust system will increase flow, possibly increase velocity, optimize exhaust scavenging, and use heat to its advantage. The whole idea is to make it easier for the piston to push the exhaust gases out of the cylinder. If it’s hard to push the gases out of the cylinder, that will resist the rotation of the crankshaft. If it’s easy to push the gasses out of the cylinder, there will still be resistant to the rotation of the engine, but with less resistance comes more power.If you have questions, please contact us.
