All the S&B owners will tell you it's better than the K&N! Lol.. The K&N is louder than the S&B from my researching on here, due to the K&N being open and S&B being closed off very similar to stock. I have read a lot of people stating the K&N is much louder but in a good way. You can't go wrong with either imo, both are good products.
