Ok, i found some reducers on google so i see what they are no. heres a pic, i assume this is what i need? (of course with the correct in and out diameters) How do you make them tho, and do you know the diameter it needs at the large end? i suppose if i got a piece of pipe from a hardware store and slit it from about 1/2 way down and bend it to form a cone that would work eh? Also, how long did you make them?
