That drag pipe on your bike is useless. The bike will have no low and midrange and will be obnoxiously loud.I have hear the naked-metal version (with blue heat marks) of that pipe and it DOES NOTHING to abate sound. It would sound exactly like the header without the part you are wondering about
It is nearly identical to my $16 pipe below in extreme noise, but ZERO droning in my helmet, so the rest of the world can love it or turn.

It looks nice but want to know how it sounds.
Thanks in advance
