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.

Good puppy toy
Color: Brown, Pattern Name: Tree stump 1 Pack
Keeps the pup busy. He is not able to bite through it, it is very durable. Only gave 4 stars because it only takes him about 15 minutes to go through it and hes onto the next thing. Love that he is not able to destroy it though like other toys.

High quality toy loved by my dogs
Color: Brown, Pattern Name: Tree stump 2 Pack
These are amazing, my dogs favorite toys now. I have two strong chewers who haven’t been able to destroy these. I use yogurt, peanut butter and eggs, broth, really any dog friendly liquids to fill it. I recommend these to all my friends and family with dogs of all sizes.

Excellent Purchase!
Color: Brown, Pattern Name: Tree stump 2 Pack, Color: Brown, Pattern Name: Tree stump 2 Pack
My dogs and I really like these treat toys! I was surprised and questioning whether to keep them when I took them from the box. They are heavier and harder and larger than I envisioned. I didn't realize how hard a nylon/coffee wood combo actually is. However, I want to emphasize that the sales description IS accurate. It details the specifications, materials and size. Clearly states that they are designed specifically for aggressive chewers. I just haven't purchased anything quite like this before. That said, I was happy it came in a 2 pack and it seems a good value for the price. The dogs have chewed on them, I can see the marks, but they haven't made a dent after about 6 treat sessions. These logs are at least as hard as antlers. They will last a long time. The silicone trays are easy to fill and freeze. I made low calorie popsicles with bone broth and some added mix-ins like pureed pumpkin, healthy freeze dried dog food topper sprinkle, etc. You could also add some peanut butter in the small open end of the log if you want. I just ran hot water over the bottom of the silicone tray to melt the freeze slightly and the frozen treats slid right out. They are shaped perfectly to fit the hole in the log. The seller provided small tools to unscrew/screw the cap in and out for filling with treats. Even the smaller of my 2 dogs (30 lb Brittany) can get her mouth around the end of the log to carry it to her bed to lay and lick/chew it. I guess another advantage, beyond the durability, of the material is that my dogs don't want to play with it like a toy. They know it is time to relax and have a treat timeout. More like chilling with a chew bone. Overall we really do love these!! Glad I tried them.
