Welcome to the Valvetronic Designs cat-back exhaust system for the F8x platform, or in other words, the solution to the F8x sound problem. For years enthusiasts have wanted to find a solution to the buzzy and raspy sound these cars produce from the factory. Since these cars were released back in the late portions of 2014 we all knew there is world class sound lying under all the rasp. Our mission has been to find this hidden sound and allow all F8x owners to enjoy it. This full catback is comprised of a 2.75" equal length mid section with an H pipe configuration. After traveling through the H pipe the exhaust is combined into a 3.5-inch axle back. This combination helps smooth the exhaust tones to provide a very enjoyable sound through the entire rev range. When operating with the valves open, the exhaust gases exit unrestricted out of the passenger side exhaust tips. With the valves closed the exhaust passes through our quad chambered muffler and out of the drivers side exhaust tips for a lower volume experience, very well suited to daily driving and not alerting the Karens. This system mounts up to factory mounting points and is a direct bolt-on. No cutting or welding necessary. It's time to make the F8x sound like it always should have.

At Valvetronic Designs, we are chasing perfection and we believe this, our equal-length exhaust setup, is the sound solution for F8x owners. Traditionally equal length exhaust configuartion lowers the aggressive nature of the S55 engine. With this new design we have spent countless hours testing to ensure the raw aggressive sound is present through all rev ranges to give that emotion, but the equal length configuration allows for the sound to be very pleasurable rather than just loud. Owners coming from other non-equal length setups will not feel short-changed in regards to this setup's volume.

In-House Development at Valvetronic Designs: Pioneering Performance Exhaust Systems

At Valvetronic Designs, we take pride in crafting performance exhaust systems that combine innovation, precision, and unmatched quality. Our in-house development process is built on cutting-edge technology and rigorous testing to deliver the ultimate driving experience. From 3D scanning to sound and performance optimization, every step in our process is engineered for excellence.

1. 3D Scanning: Precision from the Start

The foundation of our exhaust system development begins with precise 3D scanning. By capturing detailed measurements of the vehicle’s underbody, we ensure our exhaust designs integrate seamlessly with the car’s architecture. This process eliminates guesswork and allows us to create systems that fit perfectly, enhancing both performance and aesthetics.

2. CAD Design: From Concept to Reality

Once we have accurate data, our team uses advanced CAD (Computer-Aided Design) software to conceptualize and develop the exhaust system. Each system is designed with both form and function in mind, ensuring a balance of aesthetics and performance. Our engineers focus on optimizing airflow, minimizing backpressure, and creating valve systems that allow the driver to control the sound and performance with the push of a button.

3. In-House Prototyping: Bringing Ideas to Life

Prototyping is where our designs take shape. Using state-of-the-art fabrication equipment, we build prototypes of our exhaust systems in-house. This hands-on approach allows us to refine each design, ensuring it meets our high standards for quality and performance. Our team meticulously inspects and tests each prototype, making adjustments as needed to guarantee that the final product is flawless.

4. Sound & Performance Testing: Tuning for Perfection

What sets Valvetronic Designs apart is our commitment to perfecting both the sound and performance of our exhaust systems. We don’t just aim for power gains; we focus on creating a signature sound that enhances the driving experience. Using our in-house testing facilities, we measure sound levels, optimize valve operation, and analyze performance data to ensure each system delivers the ideal blend of performance and acoustics.
