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.

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.

Quality Case
Color: Pink
This is an All in Pne case. I really like the lavender color with sparkles. It is a little heavier than expected but I still love it!

Ok, but don’t use hand cream
Color: Black, Color: Black
I like the case for its ability to house the keyboard, the pencil and the iPad in one convenient place. I find that the magnetic closure and magnets holding the keyboard are not as strong as a previous case I had purchased. The keyboard is great, I like the touchpad and the backlight colors. The cover material is not hand lotion friendly! I’ve tried water and lens cleaning wipes, and neither gets this cover clean. I hesitate to use any chemicals because the material is the type that will get sticky and nasty, and I don’t like that. I’ve included a photo of what the cover looks like after using a lens cleaning wipe. If the magnets were stronger and the cover material easier to clean, I would buy again.

great case!
Color: Navy Blue
pros; the color is beautiful. I picked the navy blue. It is exactly as the description described. It goes very well with my blue iPad. The size is very precise and fits perfectly on my iPad. The magnet that holds the case together is very strong. The iPad itself can pivot vertically and horizontally using that magnet. This works very smooth. The magnet closure for the case itself is strong and holds well. The magnet that holds the keyboard in place also works very well. Cons; when the keyboard is in its correct position, it is difficult to angle the iPad in front into the provided grooves. The keyboard gets into the way. This prevents the iPad from reaching the grooves provided. The keyboard feels very light and cheap. The keyboard itself connected with the Bluetooth very easily. It works wonderful. I love the back light on the keyboard. The color of the keyboard is wonderful. However, as I said above, it does feel a bit cheap. But for 20 bucks, what can you ask for. When the case is folded together with the keyboard in the iPad, it is a bit bulky. But I knew that from the previous reviews and was expecting it. What I love most about this case is that the iPad can be removed using the magnet on the back from the keyboard portion, but it is still protected by the exterior plastic case. So in situations where I don’t need to use my keyboard, I can remove the iPad itself and know that it’s still protected overall I recommend this product.

Nice Case & Keyboard
Color: Blue
Love this case with a keyboard. I like using the keyboard vs using one on the screen of iPad. And the keyboard has rechargeable batteries instead of having to buy batteries. And it protects my iPad.

Beautiful, and everything I want it except that the keyboard keys didn’t work😭
Color: Light Pink
I searched and search for the right keyboard case for me. The most important thing for me was to be able to remove the iPad case itself from the whole case and keyboard, and this one was it. Unfortunately, when I started checking the keyboard a lot of The keys were not output in the correct symbol or letters. So defeats the whole purpose of having a keyboard. I returned it and asked for a replacement, thinking that the item was defected, but when I got the New replacement, it was the same thing so I tried to contact the seller, but there was no option to do that. Therefore, I had to return the second replacement keyboard and look for another keyboard cover.
