Dinan Valved Axleback Exhaust - Black Tips - BMW G87 M2

The Dinan Valved Axleback for the BMW G87 M2 upgrades the axleback section with 76mm tubing (vs 70mm OEM) and retains the factory exhaust valves for complete OEM integration. When the valves are closed, exhaust gases route into the Dinan muffler where absorption and reactive technologies combine to produce a deeper, more composed tone through the two inner tips without cabin intrusion. Open the valves under load and the architecture shifts: gas bypasses the muffler almost entirely through the outer exits in a near-straight-pipe configuration, maximizing volume and delivering the aggressive character the S58 is capable of. Black ceramic-coated quad tips complete the visual package.
