i have a set of fmf gold series fatty pipes that came on my bike when i got it. they are going to need to be repainted, the paint is chipping and on the expansion chambers it seems they did not use high temp. paint. they might need a repack they sound a little louder than the typical fmf pipes. there is one small dent in the left side expansion chamber, might be able to see it in the pictures. the silencers say spark arrestor on the side, but not 100% sure which ones they are (power core 2?). i only use the computer at work, so i will check them out a little better when i get home and update tomorrow with more pictures if needed. asking 150 shipped. my cell is 330-432-5912. located in mechanicstown, oh. 44651
