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. Arrow offers this exhaust as a slip-on version designed to fit the stock headers.
