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

A Breath of Fresh Air for Your Car
Size: 8.3" x 9.3" x 1.3"
This BOSCH 6037C HEPA Cabin Air Filter is a fantastic and simple upgrade for your vehicle. It delivers exactly what it promises: cleaner, fresher air inside your car. The installation was incredibly straightforward. It was a perfect fit for my Acura RDX, and I was able to swap out the old filter in just a few minutes. You don't need any special tools, making this an easy and quick DIY project for anyone. The difference in air quality is immediately noticeable. The HEPA filtration does a great job of trapping dust, pollen, and other allergens, leaving the cabin air feeling much cleaner. It also seems to reduce outside odors, which is a huge plus. Overall, this is a high-quality product that provides excellent value. It's an essential and affordable way to improve the air quality in your car. I highly recommend it for any compatible Honda or Acura model.

High quality cabin filter
Size: 8.3" x 9.3" x 1.3"
I change out the cabin filters in my cars at every oil change. It help when running the A/C all summer. This is high quality cabin filter that does its job. Seeing what the dealer wants for literally 1 minute worth of work is silly.
