I'd buy a set for my cb550 if you made one! I "made" my own set and it turned out looking and sounding great, but it's just not the same as something well engineered with performance in mind!! (I am a physicist and an engineer but there comes a time when the effort put into a design (making computer aided theoretical models using fluid dynamics) becomes way too much work! ..it's just not worth the effort when making only one set of pipes!! Hope you come out with something nice!
