Dinan Free Flow Axleback Exhaust - BMW M2 (F87) 2016-2018 - Black Tips

Dinan's Free Flow axleback system is built entirely from 304 stainless steel and dyno tuned for maximum flow with minimum backpressure. A computer controlled valve keeps the M2 quiet at low speed and opens fully under high load, where the exhaust flows straight through 3.25 inch tubing for peak power and an aggressive tone. Spent gases exit through quad 3.5 inch laser engraved black ceramic tips carrying the Dinan logo, and the system reuses the factory valve actuators, brackets, and hangers for a factory fit. Dinan rates maximum gains of 6 horsepower and 5 lb-ft of torque.
