BMW X3 / X4 Valved Sport Exhaust System

At Valvetronic Designs, we believe in offering enthusiast the ultimate experience. That is why in our pursuit to develop engineer and deliver the worlds most enjoyable sound experience for the G01 platform, we have resulted in one of our finest systems yet. Utilizing many developments from our other systems, the maximum piping diameter is used so that you get the most raw and unfiltered sound experience when the valves are opened. When the valves are open, this system is as raw as it comes. Tons of turbospool, aggressive overrun, and an unfiltered aggressive sound that sings all the way from idle to red line. Fortunately, with the valves closed, the exhaust is extremely docile and perfect for a daily use. Over 25 dB of sound difference from valves open to valves closed means that you're enjoy enjoyment of your M40i will be unwavering as this exhaust system allows you to have that much needed flexibility. Its time to let that B58 sing. At Valvetronic Designs, we never compromise, and neither should you when it comes to choosing the best exhaust system for your M40i.
