Unleash the true potential of your BMW Z4 M40i with the Valvetronic Designs Valved Exhaust System—a performance upgrade born from extensive research and development on the B58-powered platforms, including the Supra and M340i. At Valvetronic Designs, we don’t believe in compromise, and we know you don’t either. That’s why we’ve engineered the perfect exhaust setup to elevate both the performance and sound of your Z4 to an entirely new level.

Engineered for the Ultimate Sound Experience

Our exhaust system features a single 3 1/2-inch midsection, seamlessly transitioning into a dual 3-inch configuration all the way to the exhaust tips. This optimized layout significantly improves exhaust flow, enhancing both throttle response and overall engine performance. But it’s not just about power—it’s about delivering the perfect soundtrack. Inspired by our work on the legendary B58 Supra and the M340i, we’ve meticulously tuned the system to deliver a rich, aggressive tone that’s powerful on the throttle yet refined when cruising. The result? A full-bodied exhaust note that matches the performance of your BMW.

Precision Engineering for Peak Performance

We know the importance of a balanced exhaust system in unlocking the full potential of your car. Our Z4 M40i system is designed to minimize restriction, maximizing power and torque while also enhancing the driving experience. The integration of valves allows you to control the sound profile—whether you want a quiet, civilized drive or a spine-tingling roar, the choice is yours at the touch of a button.

Uncompromising Quality

At Valvetronic Designs, our mission is simple: to provide BMW enthusiasts with the best exhaust systems on the market. With years of refinement from platforms like the B58 Supra and M340i, we’ve perfected the art of creating exhausts that not only perform, but also produce the ideal acoustic experience. The result is an exhaust that offers superior flow, performance gains, and a sound that will excite every time you start your engine.

We don’t compromise on quality, and neither should you. Our systems are crafted using the highest quality materials, rigorously tested to ensure the best performance and reliability. With the Valvetronic Designs G29 Z4 M40i Valved Exhaust, you're not just upgrading your exhaust—you're transforming your driving experience.

Elevate your Z4’s sound, performance, and style with the exhaust system that enthusiasts trust. Choose Valvetronic Designs. Because your BMW deserves the best.

Great blanket!

I originally bought this to use in photos for my son’s race themed birthday. It looked perfect with the checkered pattern. But it ended up a favorite blanket in our house because it’s sooo soft!

Soft blanket
Size: Queen, Color: Ivory
Just as pictured. Soft, comforting, warm. This blanket is my favorite when I snuggle up in my chair to read. The green color washed very well, no shedding. (My child’s purple one left a lot of fuzz in the laundry, so I would advise washing that color alone.)
