Muffler ARROW Race-Tech Alu./C Kymco AK 550i E4 '17-'18

Article information

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. 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.
Race-Tech silencers are available in a street legal version.

Arrow exhaust silencer which only fits in combination with one of the two available 'header-pipes'.

Mounted together with the 'Catalytic converter' header pipe (listed as 'recommended product') this exhaust system is homologated (road-approved).

This exhaust system is performance enhancing in combination with the 'Racing Link pipe' (listed as 'additional product') but is no longer homologated then.


With homologation certificate.
