BMW X3M / X4M Valved Sport Exhaust System (F97 / F98)

For those who demand an unrivaled exhaust experience from their BMW X3M and X4M, Valvetronic Designs has crafted a system that blends precision engineering, raw emotion, and absolute control. With a deep passion for the BMW M community, we set out to create an exhaust system that not only enhances performance but also amplifies the character of the S58 engine in a way that’s both visceral and exhilarating. Our valved exhaust system is designed with no compromises—delivering the perfect balance of flexibility, sound quality, and everyday usability. Whether you’re carving canyon roads, hitting the track, or cruising through the city, this system ensures that your X3M/X4M sounds as good as it drives. Choose Your Sound: Two Distinctive Configurations 🔹 Single Mid-Pipe Configuration – The raw, unfiltered S58 experience. This design enhances the factory sound characteristics while unlocking a more aggressive and engaging tone. The deep, punchy exhaust note delivers a true M-car experience, making every drive an event. This has been one of our most sought-after systems, offering improved sound clarity, enhanced flexibility, and a more pronounced exhaust note—perfect for those who want to bring their X3M/X4M to life. 🔹 Equal-Length Resonated Full Exhaust – For those who seek something truly special, our newly developed equal-length resonated system refines the S58’s sound to exotic levels. By balancing the exhaust pulses, this configuration eliminates uneven frequencies, producing a smooth, high-pitched, motorsport-inspired tone reminiscent of European supercars. This setup transforms the driving experience, making your X3M/X4M stand out in any crowd—not just in performance, but in pure auditory bliss. Uncompromised Engineering & Seamless Integration Valved System for Total Control – Our electronically controlled valves integrate directly with the factory M1/M2 drive modes, allowing you to switch between a civilized, refined sound and an aggressive, open-throttle roar at the push of a button. For those seeking full manual control, we include an independent valve controller, letting you dictate the soundtrack of your drive. Premium Material Choices – Available in high-grade stainless steel for durability and longevity, or ultra-lightweight titanium for an even sharper, more pronounced tone. Both materials ensure maximum heat resistance, strength, and performance. True Cat-Back Performance – This system completely replaces the factory cat-back section, delivering measurable gains in power, response, and sound enhancement while maintaining daily drivability and long-term reliability.

Every product we develop is driven by a passion for performance and a deep understanding of what enthusiasts truly crave. Our relentless commitment to innovation has led us to engineer one of the finest exhaust systems available for the X3M and X4M, ensuring that your BMW M experience is taken to the next level. Whether you prefer the ferocious, high-energy sound of our Single Mid-Pipe System or the exotic, supercar-like tone of our Equal-Length Resonated System, you can’t go wrong. Both options deliver an unparalleled auditory experience, transforming your S58-powered machine into a symphony of mechanical brilliance. It’s time to elevate your BMW X3M/X4M—because driving should be more than just getting from point A to B. It should be an event.
