your not going to have hardly anybody buy a muffler for 3700. most people don't go any higher that 1500 which is supersprint race. the powerloop is less than that and only 2 ppl have it that i know of. as for the comment about 1500 being a joke, 3700 must be a joke. now your going to say it is handmade and has electronic valve system but 3700?
