Description Arrow Exhaust Race-Tech Carbon Exhaust and Stainless Steel Link Pipe. NOTE: Aprilia original exhaust system comes with an exhaust valve. Installing any of the Arrow exhausts it is needed to remove the exhaust valve. When installing any one of Arrow exhausts for RSV4 1100 Factory it is recommended to install a map / ECU deactivating valve function Race-Tech exhaust range was the first series of silencers designed with the new diamond-shaped section.This design replaced (quite completely, but not at all) in the past years the older silencers sections, oval and cylindrical. 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. Internal structure is generally made in stainless steel, TIG welding. The internal parts, the sections, the exit pipe and the rear endcap are designed to allow for the smoother flow of exhaust gases possible reducing back-pressure-generated losses.Race-Tech silencers are available in titanium, carbon fiber and aluminum. Mid-pipe material: stainless steel Silencer Material: Carbon Db Killer: YES European Approval – Euro 4 Link Pipe Homologated – EC Approved Silencer: ECE Approved Note – Photos are for illustrative purposes and features may change withough notice.
