Product Details

The Dinan Free Flow Axle-Back Exhaust transforms your 2008-2013 BMW 135i/135is with enhanced performance and an aggressive exhaust note. Engineered specifically for the N54 and N55 turbocharged inline-six engines, this performance exhaust system delivers measurable power gains while reducing weight and improving exhaust flow.

Performance Benefits:

  • +6 HP at 6600 RPM and +5 lb-ft torque at 6600 RPM
  • Lighter than factory exhaust for improved weight distribution
  • Enhanced exhaust flow reduces backpressure and improves throttle response

Construction and Design:

  • 100% 304 stainless steel construction for maximum durability and corrosion resistance
  • Proprietary drone abatement technology minimizes cabin resonance at highway speeds
  • Sportier, more aggressive exhaust tone without excessive loudness
  • Utilizes factory mounting brackets and hangers for OEM-quality fitment

This axle-back exhaust system is a direct bolt-on replacement that installs using existing mounting points, ensuring a precise fit without modification. The system is designed to deliver a refined sporty sound that enhances the driving experience without creating unpleasant drone during cruising. Backed by Dinan's reputation for BMW performance engineering, this exhaust system is an ideal upgrade for enthusiasts seeking both performance and sound enhancement.
