Race-Tech silencer was the very first exhaust made up with a dimaond shape and in the past years almost completely replaced the “old style” systems with a round of elliptical shape. The innovating diamond shape design really made Arow capable to reduce the dimensions with respect to traditional shapes, though keeping the same overall cross-section. This allowed Arrow to manage also a real weight reduction without compromising the inner volume, thus keeping the noise below an acceptable level without choking the performances. Inner parts of the silencers are made with stainless steel coupled with TIG welding technology.

All the “wet” sections (those involved by the gas flow) are kept under strict dimensional control, to optimize the gas flow. Really important feature are the rear endcaps and the gas outlet pipes: these components are designed so that outbound gas flow runs turbulence-free and to reduce counter-pressure negetive effects. Race-Tech range silencers are available in a Street Legal version for almost all the bikes and are equipped with a removalbe baffle (dB-killer). These silencers are available wuith sleeves in titanium, carbon fibre or aluminium. For some bikes, the titanium silencer is also available with the all-new rear endcap in carbon fibre.
