I have Moriwaki slip ons and they are way too loud. I am getting stock pipes but my question is whether or not to keep the moriwakis and Im just not sure what I have. If I sold em or ebayed would they fetch enough to make it worth while. If not I will keep them until my situation changes, if it ever does. From what little I can find about them they seem high dollar quality. there is very little information I can find about them. They are the rainbow colored zero titanium ones.
