Dinan High Flow Middle Exhaust BMW M3/M4 G80/G82/G83 - D660-0094
The Dinan D660-0094 High Flow Middle Exhaust is designed for 2021-2026 BMW M3/M4 G80/G82/G83 applications.
The system replaces the stock 2.75-inch mid-section with 3-inch tubing, deletes the resonators and uses a mandrel-bent X-pipe crossover to improve flow and increase exhaust volume.
Dinan uses 304 stainless steel construction and lists the system as 5 pounds lighter than stock. It is confirmed for use with the Dinan Free Flow Axle-Back and stock exhaust systems, including M Performance systems.
