Quick little sound test to reveal the difference between the Ktm stock slip on and the FMF 4.1 Slip on. Must say the video does not do the FMF justice as it sounds way more Gnarlier in real life!
Shaolin Style I have not yet done that, as far as I know you must do that wen you change the power valve, will probably do that at a later stage, just fitted the fmf megabomb aswell after making a few modifications to it, will post a video soon.
