Dinan Freeflow Axleback Exhaust System for Select 2015-2020 BMW M3 & M4 - Black Quad 3.5in Tips
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2015-2020 BMW M3 and M4 (Base, CS, and GTS).
The Dinan Freeflow Axleback Exhaust System (D660-0050-BLK) is engineered to enhance the acoustics and performance of the F8x chassis. Constructed from 100% 304 stainless steel, this system uses computer-controlled valves to provide a civilized tone during low-speed cruising and a free-flowing, aggressive note under high-load conditions. The twin 76mm secondary valves are 45% less restrictive than the OE components, contributing to a measured gain of +5 horsepower while reducing overall weight by 3 lbs compared to the factory unit. This system integrates drone abatement technologies to maintain cabin comfort and retains full M-Drive exhaust tone functionality.
- 100% 304 stainless steel construction for maximum corrosion resistance
- Twin 76mm secondary exhaust valves (45% less restrictive than OE)
- Quad 3.5-inch laser-engraved tips with a black ceramic coating
- Direct bolt-on installation using factory brackets, hangers, and actuators
- Drone abatement technology reduces cabin resonance
- Weight reduction: 3 lbs lighter than stock exhaust
- Performance increase: +5 horsepower
- MPN: D660-0050-BLK
