Overview:

Dinan engineers designed the F30 340i and F32 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. The system is built to exacting specifications to ensure the perfect fit using the factory hangers. It is made from 100% 16 gauge 304 stainless steel and will resist corrosion for years to come. The design features twin 89mm (3.5") polished or cermic black exhaust tips for a tasteful high-performance look. The factory computer-controlled exhaust valve is eliminated.

Features:

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

Good for beginners
Color: Blue
The gloves are not the greatest, the ones I received with my tumbler press are definitely nicer quality. The tape dispenser is constantly coming apart which is an easy fix but does get annoying at times. Overall it’s a cheap set of items that help with various sublimation items. Based on what you pay vs what you get, it’s worth it.
