The illustrated exhaust cap has been machined from solid aluminum block to the oem standard dimensions therefore it is an exact copy of the oem one. Additionally, it has been anodized for obvious reasons which makes it more durable to salty conditions. This exhaust cap enables the SX-R owner to use the oem plastic cap that bolts on top of it. If the exhaust cap on your ski has been corroded this one is a direct replacement unit. It costs 150euro and it is available from Champions dealership (www.championsjetski.com) in Athens, Greece.
