Dinan Free Flow Axle-Back Exhaust System with Polished Tips for BMW M5 ( F90) 2018-2023

The Dinan Free Flow Exhaust System for the BMW F90 M5 enhances the already remarkable performance of this luxury super sedan by transforming its exhaust note into a more aggressive and powerful symphony. The stock F90 M5 is known for its refined performance, but Dinan believes it deserves an exhaust note that fully matches its formidable capabilities. With this exhaust system, the M5 is given a louder and more aggressive tone without sacrificing comfort, drone control, or the refined character BMW drivers expect.

Key Features:

  • Performance Gains: +6 HP and +5 lb-ft of torque at 6600 RPM.
  • Refined Aggression: The exhaust note remains subdued during low-speed driving but becomes ferociously aggressive during hard acceleration, all while maintaining a drone-free cabin thanks to the retained computer-controlled exhaust valves.
  • Larger Piping: The exhaust system uses 83mm tubing (compared to the stock 80mm), allowing for freer flow, which improves performance and sound.
  • Improved Exhaust Flow: Dinan’s exhaust incorporates absorption and reactive technologies to reduce backpressure and optimize exhaust flow.
  • Quad Exhaust Tips: The system features four 4" (102mm) double-walled, polished exhaust tips, which are clamp-on for easy customization or replacement. These tips fill the factory cut-outs for a striking, aggressive look, while maintaining Dinan's signature straight-cut design.
  • Durable Construction: Built entirely from T304 stainless steel, the exhaust is TIG welded for superior craftsmanship and comes with a brushed finish for a sleek appearance out of the box.
  • Customizable Sound: With the stock exhaust valve actuators reused, the exhaust tone can still be adjusted through the M-drive settings, allowing the driver to switch between refined and aggressive modes based on driving conditions.
  • Larger Secondary Valves: The twin 76mm secondary exhaust valves (30% less restrictive than stock) further enhance flow and performance under load.
  • Easy Installation: A simple bolt-on design with all necessary mounting hardware ensures ease of installation.
