Dinan Free Flow Axle-Back Exhaust - 2017-2020 BMW 440i - D660-0077-BLKOverview: 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

Overview:

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. 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 ceramic 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

Craft Room Staple
Model: Kraft er Paper 002
I purchased this butcher paper for my craft room, and it has been a fantastic addition to my supplies! I primarily use it with my heat press, and it works perfectly to protect both my designs and my press during sublimation and other heat-transfer projects. The paper provides a great barrier and prevents any ink bleed-through, keeping everything clean and professional-looking. What I love about this butcher paper is its versatility. Beyond the heat press, it’s handy for a variety of other craft projects, like covering work surfaces for painting, wrapping delicate items, or even sketching out design ideas. The roll size is generous, so it lasts a long time, even with frequent use. The quality is excellent—it’s thick enough to withstand heat and pressure but still easy to cut and handle. It’s a must-have for any serious crafter or DIY enthusiast!
