Dinan Freeflow Axleback Exhaust System for 2023-2026 BMW M2 - Black Ceramic Tips (D660-0100-BLK)

Fits 2023-2026 BMW M2 (Base). This Dinan Freeflow Axleback Exhaust System is engineered to improve the exhaust note and performance of the G87 M2 without sacrificing civility. By increasing the tubing diameter to 76mm (compared to 70mm factory piping), Dinan reduces backpressure and optimizes flow throughout the system. This axleback retains the factory computer-controlled exhaust valve actuators, allowing you to adjust the exhaust tone via the M-drive settings.

When the valves are closed, gases are routed through the Dinan muffler using absorption and reactive technologies to mitigate drone and maintain a deep, subdued tone. Under high-load conditions, the open valves allow gases to bypass the muffler for a near straight-pipe flow. Constructed from 100% 304 stainless steel, this system is 6 pounds lighter than the factory exhaust and includes four 4.5-inch double-walled, black ceramic-coated tips.
