I purchased a used 2007 Harley Sportster last summer. the bike has aftermarket slip on pipes and an aftermarket air cleaner. I would like to know what make these are if anyone knows. this is my first post so I will try to upload photos. I apologize up front if I fail at this attempt. I have replaced the air filter in the air cleaner with a K&N so I am happy with it, I am just curious what it is. Also what is the purpose of the smaller air filter underneath the air cleaner. I also like the sound of the bike so I am OK with the slip-ons as well, just curious what brand they are. thank for all your help.

 

The smaller filter is for the breathers. Check it at oil changes to be sure it isn't saturated with oil. Idk on pipes maybe cycle shack. Air cleaner search JP cycles or somewhere and search till something matches.
