    Is there any way of reducing the exhaust noise of a new Robin 35? It's acceptable, but I don't want to attract attention.

    I was under the impression that the Robin was pretty quiet as is.

    On hard acceleration the Robin's exhaust is quite loud and frantic. Would a short piece of plastic or metal pipe on the end of the exhaust stub help reduce it?

    If there is a stub of tubing sticking out of the muffler, you could add 8 -12" of silicone exhaust tubing. It helps.

    Kerf:
    Have you done this on the Robin/Subaru??? If so, any performance issues? Also, where do you get the tubing? The auto parts store?
    Thanks,
