The Dinan Free Flow Axle-Back Exhaust (D660-0028) is the most technologically advanced acoustic solution for the 2008-2011 BMW M3 Sedan (E90), reflecting Dinan's pedigree as a championship-winning racing supplier. This system is engineered to solve the common compromise in performance exhausts by employing leading-edge technology, including a Helmholtz chamber and a straight-through, single-channel absorption design. This technology increases flow while effectively reducing unwanted noise and eliminating the "drone" typically experienced at light throttle cruise. The system delivers a verified power increase of +6HP and +5LB-FT of torque at 6800 RPM and is a full 10lbs lighter than the stock BMW part. This system upholds Dinan's core philosophy of "Performance Without Sacrifice," providing a sporty sound at wide-open throttle while remaining quiet and civilized for daily driving.

Features

  • Verifiable Power Gains: Delivers an increase of +6HP and +5LB-FT of torque at 6800 RPM.

  • Advanced Drone Abatement: Integrates a Helmholtz chamber and a single-channel absorption design to remove drone and reduce unwanted noise at light throttle cruise.

  • Optimized Flow & Weight: Features a single-channel "straight through" canister design and is a full 10lbs lighter than the stock exhaust.

  • Superior Material: Built from 100% 20 gauge 304 stainless steel to resist corrosion and ensure long-term durability.

  • Aesthetic Excellence: Finishes with quad 3" black ceramic coated and laser-engraved exhaust tips (polished stainless tips also available) for a high-performance look.
