Axle-Back Exhaust System with Forged Carbon Tips

The Valvetronic Designs axle-back exhaust system is engineered to enhance the acoustic profile of your BMW G8X M3 or M4, complementing its aggressive styling and performance capabilities. This system is designed to work seamlessly with OEM downpipes or free-flow front pipes, bringing out the true character of the S58 engine without triggering check-engine lights. Constructed from premium brushed T304 stainless steel, this exhaust system ensures durability and a sleek appearance. The tubing diameter measures 3.5" for the mid-pipe and 2.75" for the axle-back. Weighing 24.7 lbs less than the stock exhaust, it contributes to improved performance and handling. Key features include electronic valves with an included remote controller, offering the flexibility to switch between an aggressive growl and a quieter tone for daily driving. An option for OEM integration is also available for a cleaner look. However, if installing only one section, a cut at the second dimple on the OEM pipe is necessary for perfect fitment. This system is compatible with a range of BMW M3 and M4 models from 2022 through 2026. When you order, you will receive the valved axle-back, a controller, and distinctive Valvetronic forged carbon tips that add a touch of elegance.
