Overview

Dinan's Free Flow Axle-Back Exhaust for the M5 provides improved flow and the resulting power gains without the excessive noise associated with typical aftermarket mufflers. The Dinan exhaust features a rigid and durable muffler case, manufactured from 20 gauge-304 stainless steel for optimum resistance to corrosion. Internally, the systems feature Dinan's Tuned Resonance Chamber Technology, providing the optimum balance between maximum power gains and a civilized, yet sporty exhaust note. The system also reduces weight substantially, weighing in at only 37.6 lbs. as compared to the stock system at 66 lbs. Dual 3-inch diameter polished stainless tips give the cars a tasteful performance look as well.

Features:

  • More Power: + 6 HP @ 6500 RPM + 5 LB-FT @ 6500 RPM (w/ software)
  • Drone abatement technologies used to reduce cabin resonance
  • Enjoyably louder, sportier sound
  • Dual 3" polished and laser engraved exhaust tips
  • Over 28 lbs. lighter than stock (37.6 lbs. vs. 34 lbs.)
  • 100% 304 stainless steel construction
  • Uses the factory brackets and hangers for a factory-like fitment
