Noticeable difference. I love it. With my bike in particular, I think I wish I would have just gotten the black one. I don't know what all the differences are between the two, but I ended up painting the intake tube to match the black bottom of my bike.

Great product and quality materials, gives the bike a more aggressive look and improves engine response, especially at wide open. Sounds great as the bike accelerates. Highly recommend this product to any HD owner.
