Add 250% more Downforce to your 992 GT3 with our Valkyrie 992 GT3 Carbon Fiber Swan Neck Wing Focusing on your Porsche 911 Aerodynamics just as the factory did on the 992 GT3RS will really help the car be planted and more confidence inspiring on road and track. Designed using CFD and rigorously tested, the Dundon Valkyrie wing gives your 992 GT3 more downforce and the driver more confidence to go faster. Making the car faster and easier to drive fast: Take it from Amit P. “I went 3 seconds faster compared to my last times, and it felt more effortless. Like I didn’t change much with my own driving, just went out there as normal and the confidence in it just made that extra time.” – Amit P. The entire Dundon aero package for the 992 GT3 was designed to increase downforce while minimizing the drag coefficient. Using Computational Fluid Dynamics (CFD) allowed us to make a blade design tailored to the shapes of Porsches 911’s, Caymans and 911 Cups. A universal wing profile is fine, but a tailored wing profile is far superior. Up to 250% more maximum downforce with improved looks for your 992 GT3! With the Stock 992 GT3 wing at 12* Angle of Attack (maximum) and the Valkyrie Swan Neck Wing at 4*, we see 165% more downforce and ZERO increase in drag at 100mph. The Valkyrie Swan Neck wing at 0* makes 10% MORE downforce and 30% LESS drag than the stock 992 GT3 wing at 12* (maximum) at 100mph. While absolute numbers are great, where things count for aero isn’t 200mph numbers but 80-120mph numbers as this is generally the speed you are trying to turn the car and want your 911’s aerodynamics to really help you. Every Detail of the package was refined and designed to work together Look at the 100% Carbon Wing Ends for instance. Ours are 3 dimensional , with flowing prepreg carbon contours and cutouts to aid in vortices generation to further improve the Valkyrie wings performance. All of this leads to a faster more planted car and a more confident driver The wing risers or wing uprights for our package are unique to the package as well. Taller and farther back that stock, very close to what a 992 GT3 Cup wings position. The uprights along with substantial reinforcement to the upright supports, and chassis set this kit apart! Think the stock uprights can support substantial downforce increases? Think again… Want downforce of the 992 GT3RS without average dealer markup? Grab our Dual Dive Planes and soon to be released full Carbon Splitter for GT3RS passing grip! Check the Pictures and Shoot us a message, call or email for more info!
Take your 992 GT3 to the next level of performance with our Valykrie Carbon Swan Neck Wing Package. Designed using CFD and rigorously tested, the Dundon Valkyrie wing gives your 992 GT3 more downforce and the driver more confidence to go faster. 
Here’s a bit of science for ya! First we need to explain the the pictures a bit. This is a chart of the performance of our Valkyrie Wing. Let’s explain a few terms Down Force – The amount of force a aerodynamic device “pushes down” on the car Drag – The amount of force pulling back on the car due to the inefficiency of the downforce production. L/D – The ratio of the Downforce (lift) to Drag to understand the efficiency of the downforce created. AoA – Angle of Attack or Degree of the wing notated by the “*” in the below graph. Speed – Speed of the car in mph. Keep in mind here that 200mph numbers are neat but in reality not reasonable as when have you tried to turn the car at 200mph… First things first. Here’s the simplest explanation of the benefits
- Valkyrie at 4*, we see 165% more downforce and ZERO increase in drag at 100mph than the Stock wing at Max (12*) Angle of Attack
- Valkyrie wing at 0* makes 10% MORE downforce and 30% LESS drag than the stock wing at 12* (maximum) at 100mph.
- Placement of the Valykrie wing enhances under body aero and increases high pressure on the intake ducts.
- 3d End plates not only look great, they work to make the wing more efficient (more downforce, less drag) than flat pieces of carbon!

VALVES
All Fi-EXHAUST exhaust systems are equipped with valvetronic technology. This technology is not only used to control sound volume, but also enhance overall performance of the vehicle. Before the inception of this technology, horsepower and torque were irreconcilable contradictions in the design of exhaust systems. This allowed sports cars to have high torque power at low rev speeds and even higher horsepower capability at high rev speeds.
DOWNPIPES
Catless Standard Version
The ultra-high flow catless downpipes remove restrictive factory catalytic convertor. They increase exhaust gas flow and performance gains, produce higher sound volume. And is usually recommended option going further with ECU tuning.
Catless Sensor Version
The ultra-high flow catless downpipes remove restrictive factory catalytic convertor. They increase exhaust gas flow and performance gains, produce higher sound volume. The downpipe is also equipped with a dummy oxygen sensor to reduce a chance of the check engine light (CEL) being triggered.
Race 100Cell
This kind of catalyst is generally used in race cars , so it is often called “racing catalyst”. With the larger cells and fast exhaust flow rate, it is smooth, durable and do not have refractory wool burn-out problems. The higher the number of the cells, the smaller and denser the hole is. The higher the back pressure, the more it can enhance torque performance, while the opposite is true for increasing horsepower. Converting your stock catalyst converter (400~800 CPSI) into our metallic catalyst converters will result in significant enhancements in airflow discharge that circumvents the limitations and parameters set by car manufacturers.

MODIFICATION GUIDE
Dear car enthusiasts, today we'll delve into the latest trends in modifying exhaust systems in 2024, specifically tailored for those interested in enhancing the performance of supercars and high-performance sedans.
In this era of rapid development in the automotive industry, the rise of electric vehicles and increasingly stringent emission regulations are reshaping our driving experiences. With the widespread adoption of Otto/Gasoline Particulate Filters (OPF/GPF) and strict global enforcement against noise pollution, exhaust valvetronic technology is becoming increasingly crucial.
Adapting to Noise Regulations – Save Your Wallet
In 2023, Taiwan implemented noise technology enforcement in 21 cities and counties, issuing over 5000 fines. For instance, in the United States, New York recently passed the "Stop Spreading the Noise" act, equipping sound-sensitive cameras to capture noise exceeding 85 decibels, presenting a new challenge for modified car owners.
Here, Fi EXHAUST's Valvetronic technology becomes the key solution to this challenge. This technology allows car owners to seamlessly switch between street and track sound configurations with a simple button press. When the valve is closed, exhaust gases pass through a muffler, creating a discreet and comfortable driving experience. When the valve is fully open, it generates a distinctive, pulsating engine roar for an exhilarating experience.
For example, the Mercedes-Benz C118 CLA250, our Fi valvetronic performance exhaust system averages a 75-decibel sound. However, when the valve is open, owners can enjoy more dynamic tones and driving pleasure. Whether the db reading abides the regulations will depend on the car models and exhaust setup installed on the car. Please contact our representative to get more details about your car.
This technology empowers car owners with the ability to control vehicle noise output, easily adapting to different environments and regulations. Imagine driving your modified car through the bustling streets of New York, smoothly transitioning from refined street sounds to more aggressive tones allowed by the road conditions. Fi EXHAUST's valvetronic system not only ensures compliance with noise regulations but also enhances the driving experience by providing customizable soundtracks.
Factory-Equipped OPF (GPF) – The Sound Suppressor
Next, let's talk about the widespread adoption of OPF (Particulate Filter) in new cars. As vehicle emission control becomes increasingly crucial, this poses another challenge for us enthusiasts, as OPF is commonly referred to as a sound suppressor. Apart from muting the exhaust sound, it also reduces exhaust efficiency. Therefore, many people, when discussing new cars, opt for the removal of the OPF, thinking that cutting it off would eliminate the need to replace the entire exhaust system.
It's important to remind car enthusiasts that this type of removal procedure typically doesn't involve disassembling the entire exhaust system. Instead, it entails lifting the chassis and performing the cutting and welding process. However, this approach increases the likelihood of welding defects. If the welds are not done properly, it may result in leaks or fractures, leading to more significant issues.
Fi EXHAUST utilizes CAD technology to ensure that each exhaust system achieves optimal fluid dynamics and enhances the quality of the exhaust pipe. By employing automatic bending and 3D cutting techniques, we aim to minimize the proportion of seams. Additionally, the entire section undergoes manual TIG welding to ensure a smoother and more durable exhaust system.
Counterfeit Exhaust Systems on the Rise
A crucial reminder for car enthusiasts looking to modify their vehicles in 2024 is the proliferation of counterfeit products. Regardless of the brand, the aftermarket industry has observed this alarming trend, where counterfeit products not only exhibit poor quality but also pose potential threats to your driving safety. Therefore, learning how to distinguish genuine from fake becomes paramount.
Here are a few tips for identifying the authenticity of Fi exhaust systems:
- Understand the product components: Fi's exhaust system consists of the downpipe and mid-section (including exhaust tips). Understanding these components aids in recognizing the integrity of the product.
- Certification nameplate: Whether it's the downpipe or catback-section, Fi EXHAUST products feature a nameplate detailing the car model and serial number. If the nameplate is missing or unclear, exercise caution.
- Purchase from authorized channels: Only buy and install exhaust systems through Fi-certified modification workshops and dealerships. You can check Fi's official website for information on DEALER, ensuring you purchase genuine products and enjoy comprehensive warranty services.
- Follow official announcement: Follow Fi EXHAUST's official fan page on all socials to stay updated on the latest modification knowledge and product information.
By employing these methods, you can effectively avoid purchasing counterfeit products, ensuring that your modifications are both safe and reliable. Remember, modification is not just a means to enhance vehicle performance; it is also an expression of personality and taste. In the world of modifications, let's collectively pursue excellence and savor the thrill that modifications bring!
Lastly, let's heed the words of Fi's Director, Alan: "Modification is not only about enhancing performance but also about giving vehicles a soul." In an era constrained by regulations, modifying exhaust systems has become the key to infusing real life into performance cars.
