Fi Exhaust Valvetronic Exhaust System for Porsche 911 (991.1 / 991.2) GT3 / GT3 RS 2013-2019

The Fi Exhaust Stainless Steel Valvetronic Exhaust System for Porsche 911 991.1 / 991.2 GT3 and GT3 RS gives you direct control over sound and exhaust flow. This system is engineered for the Porsche GT3 and GT3 RS platform and uses valvetronic technology to adjust airflow instantly. You can switch between a low, controlled tone for daily driving and a more aggressive sound when you want a more engaging driving experience.

When paired with catless race headers, this Porsche 911 GT3 exhaust system can increase horsepower and torque in the 5 to 10 percent range. You will notice faster throttle response and more immediate power delivery across the RPM range. This upgrade is built for drivers who want measurable performance gains without sacrificing usability on the street.

The system works with the factory valve controls and is also compatible with the optional Fi Pro Remote Control. You can manage exhaust behavior based on how you drive. With the valves closed, exhaust gases move through the muffler to keep sound levels controlled and comfortable. Open the valves, and the system produces a deep, aggressive tone that brings out the character of the 3.8 liter flat six engine.

Each Fi Exhaust system uses precision-built muffler internals designed for the Porsche 911 991.1 and 991.2 GT3 and GT3 RS. The result is a balanced setup that supports performance, maintains drivability, and delivers a distinct exhaust note that matches the capability of the car.

Key features and benefits:

Direct bolt-on installation with no cutting required
T304 stainless steel construction for long-term durability
Improved exhaust flow for better throttle response
Refined tone with valves closed, aggressive sound with valves open
Designed specifically for Porsche 911 991.1 / 991.2 GT3 and GT3 RS

Catback Exhaust:

This system feature integrated valvetronic technology designed to give drivers control over exhaust sound while supporting engine performance across the full RPM range. With the ability to adjust valve positions, this system helps manage exhaust flow efficiently, improving responsiveness during acceleration and maintaining consistent power delivery at both low and high engine speeds.
Before valvetronic exhaust systems were developed, exhaust design often required a compromise between low-end torque and high-end horsepower. FI EXHAUST addresses this limitation by allowing vehicles to perform effectively in different driving conditions. Drivers can experience smooth power at lower RPMs and sustained output as revs increase, making this technology a practical upgrade for both street driving and performance-focused builds.

Race Headers (Optional):

Race Headers
This product is not CARB certified and may not be legal for use on emissions controlled vehicles; intended for off road use only
Race Headers may trigger a check engine light due to removal of factory catalytic converters
This product is for “off-road use only”– check your local laws & regulations regarding the modification of the exhaust system by checking the vehicle code for your state. Many states are stringent on exhaust modification laws to pass SMOG.

Fi Exhaust Pro Control (Optional):

The Fi Exhaust Pro Control System gives you full command over your valvetronic exhaust setup through a smart control box, dual-button remote, and a dedicated mobile app. Built for drivers who want quick access and consistent performance, this system integrates directly with your vehicle to manage exhaust valve behavior in real time.
The mobile app includes a built-in diagnostic feature that can scan for and clear check engine lights at startup, either manually or through automatic detection. You can also view live valve position data through a simple interface, making it easy to track how your exhaust system is operating while you drive.
With Auto Mode, you can set specific parameters based on RPM, vehicle speed, and turbo boost. Once configured, the system adjusts valve operation on its own to match driving conditions. This helps maintain the balance between sound control and performance without constant input.
The included remote control allows you to assign functions to each button, giving you direct access to open or close the valves or switch into Auto Mode. This setup puts full control in your hands, whether you are driving daily or pushing the car harder when conditions allow.

SHIPPING AND DAMAGE-

For items shipped by Creative Mods from our warehouse:

Most products leaving the Creative Mods warehouse go through careful inspection before shipping. Some items marked Do Not Repack (DNR) are sent in their original packaging and are not inspected internally. In many cases, our logistics team reinforces the manufacturer’s packaging to provide extra protection and reduce the chance of damage during transit.

Upon delivery, it is the customer’s responsibility to thoroughly inspect all items immediately, regardless of the condition of the external packaging. If there is any visible damage to the box or contents, you must photograph the damage and clearly notate it on the delivery receipt prior to signing. If you are unable to properly notate damage at the time of delivery, you must refuse the shipment. Once a package is signed for as “undamaged”, all rights to file a freight damage claim are forfeited, and Creative Mods will not be able to assist further.

All shipments are insured up to the stated value of the item(s); we cannot insure packages for more than their declared value. Any damage claim must be reported to Creative Mods in writing within 24 hours of delivery. After this period, claims, reorders, or refunds related to shipping damage cannot be processed. While we cannot guarantee the outcome of any claim, Creative Mods will support you to the fullest extent possible throughout the claims process.

For items shipped directly from manufacturers or third-party distributors:

If your order ships directly from a manufacturer or distributor, Creative Mods does not handle the packaging, shipping, or delivery. We also do not control their damage claim process. If there is a problem with your shipment, we will provide reasonable assistance should a shipping issue arise.

We strongly recommend that you follow the same inspection procedures outlined above when receiving third-party shipments. By placing your order, you acknowledge and agree to comply with all shipping and damage claim procedures required by the third-party shipper. If you would like additional information about third-party shipping insurance or procedures, please request these details prior to finalizing your order.

SHIPPING AND ORDER DELIVERY INFORMATION-

Items that are in stock within the United States whether housed at Creative Mods warehouse or at a supplier's facility are generally delivered within 7 to 10 business days for domestic orders. Special order items sourced from overseas may require significantly more time, depending on the manufacturer’s production schedule and international shipping logistics.

As a courtesy, Creative Mods provides estimated delivery windows based on our experience with manufacturers and their current shipping schedules. These estimates are meant to give you a general idea of lead times. Actual timelines can vary, depending on product availability and complexity, orders may take anywhere from 2 weeks to over 30 weeks.

Once manufactured, items are shipped to an international logistics hub and consolidated for ocean freight transport. Transit times can be between four to six weeks: approximately one week for local documentation and customs clearance, three-four weeks at sea, and one week for U.S. customs processing. Port congestion, customs delays, and carrier backlogs may further affect timelines and are entirely outside of our control.

Given the number of variables involved, all delivery timeframes are non-binding estimates and do not constitute a guaranteed delivery window. While we make every effort to provide accurate and conservative ETAs and often deliver faster than estimated, Creative Mods does not guarantee delivery dates for any special-order items.

By placing an order, you acknowledge that delivery times are estimates only and are subject to change. Orders cannot be canceled, changed, or refunded because of delays caused by manufacturing or shipping issues outside of Creative Mods’ control. Any ETA provided is for reference only and based on past experiences and feedback from manufacturers

EXTENDED STORAGE FOR ORDERS / ABANDONMENT POLICY-

When an order arrives at the Creative Mods warehouse and is ready to ship, we reach out to the customer to set up delivery. We provide up to 30 days of free storage, so customers have time to plan. After that, storage fees will be applied, and we will notify the customer before billing. Customers are still responsible for making sure their products are received within that timeframe.

Storage fees are assessed as follows (per calendar month):

$85 per larger sized boxes (bumpers, body kits, etc.)

$45 per medium sized box (hoods, exhaust, etc.)

$25 per smaller sized box

If items remain in storage for over a year, or if the storage fees add up to more than the value of the items, Creative Mods may take ownership of those items to cover the balance owed, unless other payment arrangements are agreed upon. Otherwise, storage fees will continue to build and will still be the customer’s responsibility. All parts remain the property of Creative Mods until paid for in full.

Order cancellations must be submitted in writing and approved by a manager at Creative Mods within 24 hours of order placement. Cancellations are granted at our sole discretion and are typically not permitted for special order or made to order items once procurement has begun.

Please note that some product images may include optional components, accessories, or finishing (e.g., paint) for illustrative purposes only, and may not reflect the exact specifications of the item being sold. If you have questions or need clarification, we encourage you to contact us prior to placing your order.

Sometimes pricing, shipping, or tax details on the site may not be calculated correctly. If that happens, Creative Mods will notify you prior to processing your payment. While we make every effort to ensure accuracy, we are not liable for such errors. If an error cannot be reasonably reconciled, Creative Mods reserves the right to cancel the order and issue a full refund.
