Product Details

The Dinan Free Flow Axle-Back Exhaust transforms the 2018-2023 BMW M5 with enhanced performance and an aggressive, sportier exhaust note. This premium exhaust system delivers measurable power gains of 6 horsepower at 6600 RPM and 5 lb-ft of torque at 6600 RPM through optimized exhaust flow and reduced backpressure.

Key Features:

  • 100% 304 stainless steel construction for maximum durability and corrosion resistance
  • Larger 83mm diameter piping compared to factory 80mm for increased exhaust flow
  • Twin secondary exhaust valves with 76mm diameter—30% less restrictive than OE valves
  • Four massive 4-inch diameter double-walled exhaust tips with black ceramic coating and laser engraving
  • Computer-controlled exhaust valves retain stock functionality and M-drive settings compatibility
  • Complete bolt-on installation with all necessary mounting hardware included

The factory exhaust valve actuators are reused, ensuring the valve-controlled exhaust tone remains fully adjustable through your BMW's M-drive settings. The valves limit noise during low-speed driving and open fully under high-load conditions, delivering an enjoyably louder sound when you want it while maintaining civility for daily driving.
