COMPATIBLE: (4.0L - S65B40)
2008 - 2013 BMW M3 E90/E92/E93
Welcome to Version 2 of the Valvetronic Designs E9x M3 exhaust system. Version 2 brings on new improvements that push us past the competition. First is a return to Vacuum valves. These valves have proven to be far more reliable than electronic ones. We have also improved the sound quality to give a more pure driving experience to make this system the best on the market for the E9x platform. These systems are fully mandrel bent for maximum flow and are constructed out of T304 stainless steel, the highest quality material on the market. Our dream is to offer the BMW community an incredible valved exhaust without charging the dreaded "M tax" and that dream has come true. For far too long these systems have been out of reach for most people, but no longer. This system comes with everything you need to have your E9x M3 sound like a beast on your favorite backroad, or cruise to the shops without alerting the authorities. Your time to take control of your E9X M3 sound is now.
You now have the option to pair your Valved rear section with the best sounding mid pipe all in one place.
This midpipe is quite different than most, featuring a freeflow x merge right after the transmission tunnel. This design helps allow for maximum exhaust scavenging and power gains throughout the rev range. in the front section of the mid pipe, two resonators are used in order to smooth sound tones immediately out of the engine. At the rear of the midpipe an additional two 12-inch resonators are utilized in to further smooth the exhaust sound and provide noise mitigation. We also offer a catted version of the X-pipe for those who do not want to go fully free flow. This X pipe is designed for those who want maximum sound and maximum Horsepower gains, it is not for the weak of heart.
For those who choose the catted version, you are in for a treat. A 200 CELL EURO 6 cat configuration is used for ultimate quality and flow.

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.
