The Dinan 18-23 BMW M5 Freeflow Axleback Exhaust System is a high-performance exhaust upgrade designed to enhance sound and flow for the F90 M5. Constructed with enlarged 83mm tubing (compared to the stock 80mm), it allows for increased exhaust flow and improved power output. The system features a muffler utilizing absorption and reactive technologies to optimize exhaust flow and reduce backpressure. It delivers a sporty, aggressive sound that remains civilized at low speeds thanks to computer-controlled exhaust valves that limit noise during daily driving and open fully under hard acceleration for a more pronounced tone. Engineered to minimize low-RPM drone, this exhaust provides a refined balance of aggressive sound and civility, often described as "refined aggression."
Designed specifically for 2018 to 2023 BMW M5 models, this axleback system is a direct bolt-on upgrade that enhances performance and sound. It is compatible with the F90 chassis equipped with the stock exhaust setup, serving as an easy replacement or upgrade for enthusiasts seeking a sportier exhaust note without sacrificing daily comfort. The kit includes the polished exhaust components, ensuring a durable and visually appealing finish. Ideal for street and spirited driving, this system improves exhaust flow and sound characteristics while maintaining the vehicle’s refined interior environment.
