Arrow Race-Tech exhaust range was the first series of silencers
designed with the new diamond-shaped section. The advanced profile
(looks like a diamond, with smooth corners) makes it possible to reduce
dimensions with respect to an exhaust with a more traditional shape and
with an equivalent section surface.

This feature is important in reducing weight and dimensions,
increasing the internal volume with excellent advantages in noise
damping and high performance. The internal parts, the sections, the exit
pipe and the rear end cap are designed to allow for the smoother flow
of exhaust gases possible reducing back-pressure-generated losses.
Race-Tech silencers include a removable baffle
