Arrow 71221CKZ Competition Full Exhaust, Collector Inox for Yamaha YZF-R3 (2021-)

Arrow's 71221CKZ Competition Full Exhaust, Collector Inox with Carbon End Cap is made specifically for Yamaha YZF-R3 (2021-current).

Competition exhausts are designed and developed specially for bikes and engines tuned for races, on the basis of the experience made in track races all over the World: these exhausts are a direct evolution of the ones used in SBK and SS bikes. Competition exhausts are made with the deepest attention to details, they ensure to exploit with the best possible efficiency engines tuned for races: bigger sections, section changes finely designed and shaped, special silencers, top-quality materials.

These exhausts are welded manually (TIG process) and are available in a "full titanium" version or with collectors and manifolds in stainless steel and silencer and link pipe in titanium. In all cases a built-in sensor plug is available, to be able to check ECU settings and make necessary modifications if needed. The sections of the various silencers available give the best performance and the best compromise between performance, dimensions and noise (noise must meet race rules limits).

Style is completed with the carbon endcap and the silencer, depending on application, can be fitted with a removable baffle. Competition exhausts are the top-level exhausts in the market, for style, technology and performance.

Last generation of street bikes are made following a precise design and style idea, giving a fundamental importance in using the smaller exhaust systems possible, placed in some "non-conventional" position. These styling and design features have an impact also on after-market parts, to use the smallest exhausts possible. Arrow decided to use for several street bikes' silencers a section initially designed for a completely different "world" and the Street-Thunder range was born.

Street Thunder silencers are available in titanium, carbon fiber and aluminum, with the endcap (with a fully renewed design) available in stainless steel or carbon. To compensate for the lower internal volume, research and tests have been done on racetracks and in Arrow’s R&D, looking for the better materials available in the market for noise reduction.

Street Thunder silencer are light and powerful, they are available as slip on systems or as a part of the full system (with Arrow collectors) and are available also in a street legal versions.
