    The cr500 exhaust manifold is a nice edition to my cr500 seals really good no leaks. The only problem i had is if you flood the bike and leave it for a while the oring rubber completely destroyed from touching raw fuel and the manifold started to leak. Then i replaced with the spare orings now everything is fine. But yeah the orings don’t like raw fuel maybe something to think about other than that love the product and look forward to more innovative products for these old big bores. Cheers Kane Martin from Australia.

    The parts arrived quickly and everything fit perfect. The CR 500 rips even harder.
