Exhaust Muffler Adventure 1050/1090 Maxi Race Tech Approved
Arrow Maxi Race-Tech 71809 silencers have been designed to match the need of a bigger volume silencer, to be used on bigger bikes, single and twin cylinders engines and when power and noise requirements are stiffer than usual. It has the same technical features of the Race-Tech, but with a larger cross-section. The larger volume is also useful for the construction of exhausts for big bikes single exhaust, generally more demanding with regard to the reduction of noise. 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. Maxi Race-Tech silencers are available in titanium, carbon fiber and aluminum. Aluminum is available in 3 different finishes: transparent anodized, black anodized (“Dark” version) and white painted (“White” version). Rear endcap is available in stainless steel or in carbon fiber. Arrow EU approved exhausts have rear cap removable (Db-killer) and are supplied with certificate of approval to be attached to the vehicle registration certificate. Removal of Db-killer transforms the silencer from homologated to racing, generating a performance improvement, but lost the approval compliance. The assembly does not require changes to the carburation, mappings or the use of additional units. NOTES: silencer fit on original and Arrow collectors
