I had similar noise on my syncro after I bashed that transverse pipe
that runs under the muffler. It was hitting the muffler brackets under
certain conditions (engine load at mid rpm) and drove me nuts tracking
it down. I fiddled with the muffler brackets and pried the (slightly
bent) pipe away to fix it.
