Good question, also do they come with a T fitting since Subaru's have two heads? If not, the hoses that have come with the CC's I've found you can get at most any hardware store. Or you could order flourosilicone hose in proper size, normal silicone will degrade under oil exposure. That little tidbit of information took me a week of communication with Hose Techniques and it comes in very limited colors.
Also, what kind of mounting solution does the mFactory catch can come with? Can we get pictures of it?
