Reviews:
The valve design
serves to reduce the The valve designs serves to
reduce the too aggressive tone which
is a common problem for most full titanium
exhausts.
While giving up a
bit of high end flow the valve system at closed
more offers a much milder tone which you want it
when you are cruising downtown or don't want to
draw too much attention.
When the valve is
set open, you get what a full titanium exhaust
should offer, trademark aggressive tone and total
free flow power gain.
To optimized the
performance, Ki'S RACING X pipe is recommended to
work with the valved version.
