there are 4 copper gaskets used on our 4 cylinder bike. and its part # 11060-1203. you gave him the part # for the gasket that goes after the cat and the one after the uptube the the actual exhaust can slides into. Please be more careful before guessing with part #. I know everyone should double check for themselves but it would majorly suck if someone ordered the wrong part based on what someone said.If you need a part# I believe it's 11060-1330 you need two.
