[CL9] Need Help with Modifications

Why not jtune. The pipe is the same size from the airfilter to the pipe and its only 400. It comes with a k&n airfilter also

because for that price that comes with an k&n airfilter I rather just DIY or actually buy an intake that doesn't use k&n unless I'm wrong about their gains.

Maybe I've been informed wrong but I've always thought Injen or Comptech
