Product Details

The Dinan Free Flow Axle-Back Exhaust transforms your BMW 325i or 330i with performance-oriented exhaust tuning that delivers an enjoyably louder, sportier sound without excessive drone. This direct bolt-on upgrade enhances your driving experience with refined acoustics and measurable weight savings.

Key Features:

  • Premium 100% 304 stainless steel construction for durability and corrosion resistance
  • 39% weight reduction over stock—11 lbs. lighter (17 lbs. vs. 28 lbs. factory exhaust)
  • Dual 2.5-inch polished exhaust tips with laser-engraved Dinan branding
  • Proprietary drone abatement technology minimizes unwanted cabin resonance
  • Uses factory brackets and hangers for OEM-quality fitment and easy installation
  • Deeper, more aggressive exhaust note that enhances the driving experience

This axle-back exhaust system installs using your vehicle's existing mounting points, ensuring a secure, factory-like fit with no modifications required. The precision-engineered design maintains proper ground clearance while delivering the performance sound enthusiasts demand.
