FMF 2 stroke Fatty pipe. About 40 hours on it. Included is P3 Carbon fiber pipe guard ($150 free value)! There is only one small ding in it that can be seen in second picture. About the size of a quarter. The larger depression you see under the hose clamp the other picture. Was made by FMF and is supposed to be there to make it fit the bike correctly. Great pipe for low end power. If you have any questions just let me know.
