Dinan Valved Axle-Back Exhaust for 2023-2026 BMW M2 G87 - D660-0100-BLK

Give your G87 BMW M2 a deeper, more aggressive exhaust note while retaining factory-controlled valve operation with the Dinan D660-0100-BLK Valved Axle-Back Exhaust. Designed specifically for the 2023-2026 BMW M2, this performance exhaust features TIG-welded T304 stainless steel construction, larger 76mm piping, retained factory exhaust valves, and four massive 4.5-inch black ceramic coated exhaust tips. Dinan reports maximum gains of 6 HP and 5 lb-ft of torque while reducing axle-back weight by approximately 6 pounds compared with stock.

The Dinan system increases pipe diameter from the factory 70mm to 76mm to improve exhaust flow and reduce backpressure. With the valves closed, exhaust gases are routed through the Dinan muffler and exit the two inner tips for a deeper but more subdued tone during lower-speed driving. Under high-load conditions, the factory-controlled valves open and allow the majority of exhaust flow to bypass the muffler for a louder, freer-flowing exhaust note. The stock valve actuators are reused, so exhaust valve operation remains integrated with the vehicle's factory M Drive settings.
