Hello all I have a log splitter with a GX390 engine (13 HP) and its
very noisey, was just wondering if anyone knows of a way to quiet the
thing down?

Relatively little of the noise is exhaust noise; going on a muffler hunt
probably isn't going to be very satisfying.

Honda GX engines are some of the quietest single-cylinder small engines
available. If it's newly noisy, I'd look for a cause; if it's as it's
been since new, you've probably already got it pretty good.
