I bought a used fatty pipe and power core 2 silencer off craigslist was at work had roommate pay and pick it up for me, when I got home I found that the fatty pipe is damaged quite bad a fist size dent right on top of the fmf logo plus it don't come with all the parts the silencer seems to be fine. My question is can I run the silencer with my stock pipe will it make any difference and does any one know if its possible to fix a fmf pipe with a dent and how hard will it be to find the missing parts? Thanks in advance for any and all info
