Dinan Freeflow Axleback Exhaust System with Black Ceramic Tips for BMW M5 2018-2023
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2018-2023 BMW M5 Base, Competition, and CS models. This Dinan Freeflow Axleback Exhaust System (D660-0079-BLK) is engineered to optimize exhaust flow and provide a sophisticated, sporty tone. By increasing the main tubing diameter to 83mm (up from 80mm stock), Dinan reduces backpressure and unlocks additional performance while maintaining interior cabin comfort.
Constructed from 100% 304 stainless steel, the system features a muffler designed with absorption and reactive technologies to eliminate low-RPM drone. It retains the computer-controlled factory exhaust valves, allowing the vehicle to remain quiet during low-load cruising and open fully for maximum flow under acceleration. The twin secondary exhaust valves are enlarged to 76mm, offering 30% less restriction than the original equipment.
- Direct bolt-on installation with included mounting hardware
- 83mm diameter piping for increased flow and reduced backpressure
- Four 4-inch double-walled, black ceramic-coated, and laser-engraved tips
- Retains factory valve actuators and M-drive sound adjustments
- Performance gains: +6 HP and +5 lb-ft torque at 6600 RPM
- Manufacturer Part Number: D660-0079-BLK
