COMPATIBLE: (4.4L - S63B44T2)

2014 - 2018 BMW X5 M F85 

2015 - 2019 BMW X6 M F86

Welcome to the full exhaust suite for the BMW F85/F86 platform. Connecting to stock or aftermarket free flow downpipes, the valved exhaust measures 2.75 inches from inlet to outlet. This system runs unrestricted all the way back to the tips. In our testing and development of this platform, we found that running the setup unresonated provided a more raw sound experience and insane snaps when you change gears. This system reuses the OEM factory electronic valves. The system is available in T-304 Stainless steel. The S63 sounds decent from the factory but at Valvetronic Designs, decent doesn't cut it.

• Constructed from T304 Stainless Steel

• Your choice of exhaust tips 3.5 inch outlets

• Electronic exhaust valves with Controller for factory-like operation

• 9.8 lbs. Lighter than the factory exhaust

• Fully Mandrel bend for maximum flow

• Precision tig welds for high strength

• 100% REVERSIBLE, always able to go back to stock at any time

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.
