2011 KX450F Slasher Full Exhaust Run 

Please tell me he isn't trying to turn the left grip for throttle at 0:08

How loud is it compared to other systems like fmf or pro circuit? Loud is what I like

That is kinda hot. I imagine you thrusting down on the kickstarter and getting that beast fired up... I kinda want to ride two up with you!

What jets did you use when you rejetted it? I am thinking about getting the slasher exhaust for my 2007 wr250f and I would like to know if I should rejet it or not. I really like your bike btw

its not even loud..my 09 full acra can stop your heart from db..shes the loudest by far bike
