Perfect fit
Everything you could need is included. It installed in minutes and was a perfect fit. I could not be happier and my pressure washer looks great. The OEM muffler broke off.

Fit motor just right.
I have a Honda GX340 that I've had for several years, it was a bit of a tug getting the old nuts off of the mounting studs, but didn't break one off...... this muffler went right on with no problem. Of course, time will tell as to its goodness. It's a good replacement for the expense.
