Dinan Free Flow Axle-Back Exhaust System with Black Tips for BMW M240i (F22/F23) 2017-2021
Special Note: Factory computer-controlled exhaust valve is eliminated.
Dinan's Free Flow Axle-Back Exhaust System for the F22/F23 BMW M240i is engineered to boost performance by optimizing exhaust flow and reducing back pressure, resulting in gains of +6 HP and +5 lb-ft of torque at 6600 RPM. The exhaust system delivers a refined yet sporty sound, remaining civilized during everyday driving but becoming pleasantly aggressive under hard acceleration. It also features intoxicating burbles and pops to enhance the driving experience.
A Helmholtz chamber is integrated into the design to eliminate drone at low RPM, making for a more comfortable cabin experience. Built from 100% 16-gauge 304 stainless steel, the exhaust system is designed to last, resisting corrosion while offering a factory-like fit with the use of existing hangers and brackets. The system's twin 89mm (3.5") polished or ceramic black tips add a tasteful, high-performance aesthetic to the vehicle.
