Dinan engineers designed the F33/F36 440i exhaust to improve exhaust flow by reducing back pressure, resulting in increased power output and a great sporty sound that is civilized when you want it to be, and pleasantly aggressive under hard acceleration. Not only is the tone improved but the additional burbles and pops that come with it are simply intoxicating. Dinan also incorporates a Helmholtz chamber design that reduces resonance or"drone" at low RPM.

Installation Instructions
  • Twin 89mm (3.5") laser engraved, polished or ceramic black exhaust tips
  • Uses the factory brackets and hangers for a factory-like fitment
  • More Power: + 6 HP @ 6600 RPM, + 5 LB-FT @ 6600 RPM
  • 100% 304 stainless steel construction
  • Helmholtz chamber to reduce drone
  • Enjoyably louder, sportier sound
