Kawasaki ER6N M4 GP Exhaust

Kawasaki ER6N Exhaust (Stock vs M4 GP Exhaust) I did not rev it that much because it was loud and I dont want to disturb the peace in the neighborhood. Please watch my second video where I did hit the rev limiter few times to test this M4 GP Exhaust. If your interested in ordering this (only those residing in Malaysia), please contact me at FB : Thanks!
