Hey to everyone, I just joined the forum a couple of days ago. I bought a 2012 Stryker about a week ago and i love it. I used to ride a 2005 R6 but made the best decision by buy the Stryker. The forum has been great and given me a lot of ideas. The first two items that i want to do is change the exhaust pipes and the air filter cleaner. I have noticed alot of members talking about tuning and things like that. I am not too hande with these types of things so i want to do it right. If i change the pipes and air filter what else do i need to do to make it right?
