OVERVIEW
The Dinan Valved Axle-Back Exhaust for the G87 M2 opens up flow and deepens the exhaust note while retaining full control over volume through the factory-style electronic valve. Built to replace the factory axle-back section, it keeps OEM-quality fit and finish and drops noticeable weight over the stock system.
