Yoshimura Alpha Street Series Works Slip-On Muffler SS/CF

Without knowing what machine it is that you have, it's impossible to say. I can tell you that all Street Series exhaust components, such as this Alpha slip-on muffler, from Yoshimura are legally considered stock replacement parts that do not tamper with emissions controls on any machine you see listed in our fit guide. That is to say, the muffler will produce about the same sound output as the OEM unit for any machine you select from our fit guide. This makes them especially suitable for use on machines that require routine inspection for road use in the USA.
