I got the 08 and I'm gonna go with the Brocks! I researched several different pipes, but when I read all the information that Brocks has on their website, I called. The customer service was UNBELIEVABLE!!! VERY knowledgeable staff, and if you add a Power Commander with your order, you get a discount, and they preset the Power Commander to YOUR usage that you discuss with the rep. Absolutely AWESOME people to deal with, so they will be getting my business. PLUS, a lifetime support of mapping for the system as long as you own the bike!
