Upgrade the exhaust flow and sound of your F95 BMW X5 M or F96 BMW X6 M with the Dinan D660-0092 High-Flow Middle Exhaust. This full mid-section kit removes the hydro-formed factory center section and resonator, replacing them with larger 3.25-inch T304 stainless steel tubing for improved flow and a more responsive exhaust character. Designed for 2020-2023 BMW X5 M and X6 M applications, the system provides a direct, factory-like installation with included mounting hardware.
At the center of the system is a handcrafted X-pipe constructed from mandrel-bent tubing. Unlike stamped crossover designs, the Dinan X-pipe is engineered to minimize restriction and promote smoother, more even exhaust flow between both banks. This helps reduce unwanted sound irregularities created by uneven factory exhaust flow while producing a louder, fuller, and sportier exhaust note. The resonator delete further increases volume without sacrificing the refined character expected from a Dinan exhaust component.
The Dinan D660-0092 is constructed from durable 304 stainless steel and uses 3.25-inch tubing in place of the factory 80 mm tubing for enhanced free-flow capability. No cutting is required when paired with the Dinan Free Flow Axle Back system. The middle exhaust is also confirmed compatible with the Dinan Free Flow Axle Back and stock exhaust systems; fitment with other axle-back units is not guaranteed. This product is not CARB approved and may require emissions-compliance verification before installation or use.
