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.

Perfect toddler summer sandal!
Size: 6 Toddler, Color: Navy, Size: 6 Toddler, Color: Navy
My toddler loves them. Even though they are a little big for him (which I meant to buy a bigger size) the adjustable strap allows me tighten them enough so he doesn’t slide. Color goes with everything! Perfect summer shoe!

I liked them, toddler did not
Size: 7 Toddler, Color: Navy
I thought these were cute shoes. They were sturdy, protective, and flexible for little walkers. And they were pretty soft on the inside to wear without socks. Unfortunately, my two year old did not agree. He cried "don't like it" and immediately ripped them off every time I tried them on him. Maybe it's just my picky son. TTS/half size big.

Great looking shoe!
Size: 11 Little Kid, Color: Tan, Size: 11 Little Kid, Color: Tan
We got these sandals specifically for our Caribbean vacation over thanksgiving break. They run true to size but I did get them one size bigger to hopefully last for next summer as well. They look great on and go with everything! My son said they feel very comfortable on his feet and he likes easy on/off due to Velcro closure.

The Perfect Sandal for Active Kids!
Size: 8 Toddler, Color: Navy
I recently purchased the Stride Rite 360 Boy's Paddy Sandal for my son, and I couldn't be happier with my decision! From the moment he slipped his feet into these sandals, I could tell we were both going to be very pleased. Comfort & Fit: 5/5 - The Paddy Sandal has surpassed all expectations in terms of comfort and fit. The adjustable straps make it incredibly easy to get a snug, perfect fit for my son's feet, ensuring the sandals stay securely on, no matter how much running and jumping he does. The soles are cushioned just right, offering support without sacrificing flexibility, which is essential for a growing child. Durability: 5/5 - Stride Rite has always been synonymous with quality, and these sandals are no exception. They've endured days at the park, sandy beaches, and endless pavement adventures, yet they show minimal wear and tear. The materials are top-notch, promising many more months of active use. Ease of Use: 5/5 - For busy parents, the ease with which these sandals can be put on and taken off is a huge relief. The hook and loop closure is strong and stays in place, but it's simple enough for my son to handle on his own, fostering his independence. Overall Experience: 5/5 - It's rare to find a shoe that ticks all the boxes for both parent and child, but the Stride Rite 360 Boy's Paddy Sandal does just that. They've been a fantastic investment in my son's summer wardrobe and overall comfort during his daily activities. I would highly recommend these sandals to any parent looking for a reliable, comfortable, and stylish option for their child. Stride Rite has outdone themselves once again!
