haha sorry late reply working = ="
i always

to the sound of yamaha R1 /R6 and zx6r , even

when its already change the exhaust muffler
and love the superbike aura look

, especially those riders pass by your car wave at you or some just got down from his/her superbike with them full helmet on and black riding jacket
my usage is like weekend ride ,go up genting and cameron ( love hill roads)
sometimes jam up badly during holidays still wont stop me from heading down north or south for holidays
and sometimes short distance go shopping malls easier find parking.
coz i tested my friends er6f during stock and after modifying Yoshimura exhaust , still feel the sound is missing something not as good as those superbike deep , evil bass
er6n missing two piston .. . ..
