Hello Scott, Thank you for the question. According to the Website Availability, this is a Special Order part. This means we do not keep them in stock and order them in from Husqvarna once we have an order for one. As long as Husqvarna has stock ready to ship, this takes about 10-15 Business Days for the part to arrive at the Warehouse and approximately 3-7 business days to ship out and arrive to you. We hope this helps!

The engine had loosened up and it caused the twin pipes going into the muffler to open up the holes around the twin pipes and the muffler became very loud.

I removed the damaged muffler, which just took a socket set and a wrench to remove 5 or 6 bolts, and installed the new muffler. Now it sounds like it did when it was new. It was an easy fix.
