Its more silent than most of the performance pipe at high rpm full throttle.
I'll do some detail write up and review once the pipe is officially launched. It's a promise

For Penang kia, I have the pipe on my bike now, you guys wanna try out, js PM me.
it means camshaft.
see, there are 3 main things to change an engine powerband:
1) camshaft. it is at the cylinder head to control the valve opening and closing time.
2) cylinder head porting --> make your intake and exhaust bigger to allow more gas flow in and out.
3) exhaust pipe --> how to efficiently extract foul gas out of engine chamber.
1st one hard to find a street use one, most of the camshaft are stage 4 in Msia, which means low to mid end sux.
2nd one is easier, but we really need a pro who knows about cylinder head porting. a slight mistake and no turning back.
3rd one, hard to find a good one, which gives u power + pass JPJ roadblock.
