Dinan 23-26 BMW M2 (G87) Valved Axleback Exhaust System - Black Tips

To achieve desired sound volume and tone worthy of the G87 M2 the tubing was enlarged to 76mm (vs 70mm stock) to allow freer flow, and reduce backpressure, throughout the entirety of the system. The larger piping gives way to multiple pathways as it nears the rear of the vehicle -- the choice of which is utilized determined by the factory exhaust valves which are retained. When valves are closed, flow is directed into the Dinan muffler, where absorption and reactive technologies are used, and exit out the two inner tips. This limits noise during low-speed driving and produces a more subdued, albeit deeper, and agreeable note. However, when the valves are open during high-load conditions the bulk of the gases bypass the muffler altogether for a near straight pipe design and maximum aural enjoyment to be achieved. It's the perfect marriage for all tastes and allows civility or impassioned aggression depending on what the situation demands. The combination is one Dinan has deemed fitting for the marques signature performance models that cater to the tasteful enthusiast who demand the best for all situations.

• Stock exhaust valve actuators reused, and operation of exhaust valve is unchanged so exhaust tone can be adjusted via the M-drive settings
• Computer controlled exhaust valves are retained and limit noise during low-speed driving and open fully during high-load conditions
• Four, diffuser filling, 4.5-inch (114mm) double-walled, black ceramic coated clamp-on tips with laser engraved Dinan logo
• 6-pounds lighter than the stock axle back (Stock: 44-pounds vs. Dinan: 38-pounds)
• Drone abatement technologies used to reduce cabin resonance
• Larger diameter piping for increased flow (76mm vs. 70mm)
• Factory-like fitment with included mounting hardware
• Maximum gains of +6 HP and +5 lb-ft of torque
• 100% 304 Stainless Steel construction
