full fmf gold serirs wont mount

That hanger is the stock hanger which you will need.However they are stock on all blasters so most likely you already have one.Take a look under the front hood right next to the stem.You will see where that mounts to and most likely you will see that same mount already bolted up.If you have this mount you are good to go with just what is in the ebay add.If this mount is not there then I would deffinatley get one.All inframe aftermarket pipes utilize this factory mount.Main thing is to make sure whatever pipe you buy that it comes with a flange.
 
ya mac is right! mine came lose after about 3 days of having it on! when i first got mine on it was a tight tight fit but youll love it! the sound is:D
