Arrow's 71179HKR Indy Race Half System Exhaust, Titanium with Titanium Link Pipe is made specifically for Yamaha YZF-R1 (2017-2021).
Yamaha YZF-R1 2017-2021 Titanium Half System Kit With Indy Race Silencer
Indy-Race silencers were designed to be used on certain applications, mainly those requiring an under-seat silencer (making it difficult to use other Arrow's available sections), but once available Indy-Race silencers were used also in some "standard" systems.
Design has been inspired by the shape of certain US racetracks (this is the reason for the name of the range) and the section makes it possible to reduce dimensions whilst keeping a good internal volume to damp the noise with a very good power output. Internal parts are in stainless steel, TIG/MIG welded, the silencer body is available in titanium, carbon fiber and aluminum and a carbon endcap is also available as a choice.
Indy-Race silencers are available in a street legal version.
Note: Does not meet CARB (California Air Resources Board) emissions standards. For "Competition" use only. Will not ship to California.
