hey, I'm here is not to advertise this item,but just make wonder. If some one is using this type of setting.It consists of two exhausts dat can be change from 1 to the other by automatically/manually.
so at low rpm,we can use silent type of muffler.n at high rpm,we can use rempit style of muffler.

i have the site,but not from zerotohundred.


Performance Parts Classified - Speed Sound System


its the only website that i can find.
so, may i know where to install 1 around KL that is cheaper.
