Product Details

The Dinan Free Flow Axle-Back Exhaust System is engineered to enhance the performance and sound of 2015-2019 BMW X5M and X6M models. This premium exhaust upgrade delivers noticeable power gains while maintaining civilized driving characteristics through intelligent design and advanced engineering.

Performance Gains:

  • Adds 8 horsepower at 6000 RPM
  • Increases torque by 7 lb-ft at 6000 RPM
  • Optimized flow reduces back pressure for improved throttle response

Key Features:

  • 100% 304 stainless steel construction for long-lasting durability and corrosion resistance
  • Helmholtz resonator chamber eliminates interior drone for comfortable highway cruising
  • Computer-controlled valve system limits noise during low-speed driving and opens fully under high-load conditions
  • Quad 89mm (3.5-inch) laser-engraved exhaust tips available in polished or ceramic black finish
  • Direct bolt-on installation uses factory brackets and hangers for OEM-quality fitment
  • Deep, aggressive growl enhances the sporty character without being obnoxious

This axle-back system transforms your BMW's exhaust note into an enjoyably louder, more aggressive tone that matches the performance capabilities of the X5M and X6M platforms. The intelligent valve control ensures you get the best of both worlds—refined when you want it, unleashed when you need it.
