hmm unique motorsports?

 

have some bad experience over there........

think i will try K&T as recommended by one of my friends... thanks anyway!

[Guest snowdog]

i had my cone removed.. as for the small silencer.. which is it?

 

Small silencer is at the tip of the outlet. Earlier models cannot be removed but the latest model ones can be removed as there is only a bolt tightening the silencer.

 

If yours is the earlier batch, you still can remove it but cutting it away if i am not wrong.

 

[norishimu]

K&T is great nevertheless!

But they r busy... so ya...

at times got long queue there...

oh mine is d earlier batch! darn...

but nvm.. loud enuf le.. hehe..

2 loud will attract our bros in white n blue.. LOL..

[Blackbeauty69]

definately and more smooth... as now my pipe is straight thru. took out my funnel and silencer. if i put on my silencer the sound will decrease by abit only but still loud, when opening trottle not that smooth. so i rather take out my silencer.
