Overview:

Utilizing the same muffler as its B58 siblings the G30 540i exhaust improves 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 also accompany it are simply intoxicating. While on the exterior the sound may be viewed as aggressive the inside of the cabin is still civil courtesy of an incorporated Helmholtz chamber design that reduces resonance or"drone" at low RPM. While sound is of the utmost importance for any exhaust system the fit and finish are nearly equally as vital. The system is built to exacting specifications to ensure perfect fit using the factory hangers and is made from 100% 16 gauge 304 stainless steel that will resist corrosion for years to come. What is most different about the 540i system however is a completely new tip design from anything Dinan has done prior. The use of twin, massive quadrilateral, black ceramic coated and engraved angled tips are hard not to to take notice of. With over 8" of width and 4" of height per tip, the rear of the 540i assumes a more aggressive demeanor with the Dinan exhaust system. A high-performance look that marries well with the tonal makeover.

Features:

  • More Power: + 6 HP @ 6600 RPM, + 5 LB-FT @ 6600 RPM
  • Helmholtz chamber to reduce drone
  • Enjoyably louder, sportier sound
  • 2 massive quadrilateral black ceramic coated tips with laser engraved Dinan logo

My favorite new mineral sunscreen!
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
This is my favorite new mineral sunscreen! I've been searching for years for a product that is easy to apply, not messy, and doesn't show up too white. This roll-on is the perfect solution. I keep it near the front door and quickly roll the sunscreen on my hands, arms, and chest before leaving the house. The sunscreen applies so quickly and uniformly-- there are no bare spots or messy globs to rub in. Also, the roll-on keeps the sunscreen from oozing out of the tube and getting all over everything. Finally, the roll-on method also eliminates the frustration of having half-filled tubes and pumps where you can't even access the sunscreen when the tube gets low. Here's hoping this doesn't happen with the roll-on. Thank you Sun Bum for creating this wonderful product. I also love the reasonable price.

great product - it must be blended in well
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
Love this stuff. The roll-on makes it easy to apply on the go. It leaves a white streak unless you blend it in. I don't mind the white streak - at least I know I applied the product.
