Dinan Free Flow Axle Back Exhaust | 2017-2020 BMW M240i (D660-0067) Dinan

2017-2020 BMW M240I Stainless Steel Free Flow Axle Back Exhaust by Dinan

Dinan engineers designed the F22/F23 M240i exhaust to improve exhaust flow by reducing

back pressure, resulting in increased power output and a great sporty sound that is civilized when you

want it to be, and pleasantly aggressive under hard acceleration. Not only is the tone improved but the

additional burbles and pops that come with it are simply intoxicating. Dinan also incorporates a

Helmholtz chamber design that reduces resonance or”drone” at low RPM.

The system is built to exacting specifications to ensure the perfect fit using the

factory hangers. It is made from 100% 16 gauge 304 stainless steel and will resist corrosion for years to

come. The design features twin 89mm (3.5″) polished or ceramic black exhaust tips for a tasteful high-

performance look.
