chris, by "homemade" i was referring to the pipes that motion left and motomatic make, not something you need to make yourself. "handmade" would have been a better adjective than homemade.
just to make sure i'm making sense...
homemade/handmade with love = motomatic, motion left mopeds pipes
mass produced factory pipes = simo, homoet, etc.
buy one from motion left or motomatic.
