so i finally decided to get a stack for my truck. I'm gunna go for a single 5" turn out so i don't have to deal with rain. Im going to order all of the parts frim airflo.com but i don't know exactly what parts i should get. All of the inner and outer diameter stuff is confusing me. Also, what kind of clamps do i use to attach the stack to the bed and how do i do it. Sorry for all the ?'s but thank you for all of the answers.
