Does this fit my product?Questions & Answers for Muffler Asm Twin
I'd like to know if this is it in stock item in the average time to have it delivered to North Carolina?

for model number Husqvarna muffler 539131604
asked on 2023-05-18
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.

All our customer repair instructions are solicited directly from other customers just like you who have purchased and replaced this exact part. While we moderate these reviews for profanity, offensive language or personally identifiable information, these reviews are posted exactly as submitted and no alterations are made by our team.
Based on data from past customer purchasing behaviors, these parts are most commonly purchased together along with the part you are viewing. These parts may be necessary or helpful to replace to complete your current repair.
All our installation videos are created and produced in collaboration with our in-house repair technician, Mark Sodja, who has helped millions of eReplacementParts customers over the last 13 years repair their products. Mark has years of experience in selling and repairing both commercial and residential products with a specialty in gas-powered equipment.
This data is collected from customers who submitted a repair instruction after replacing this exact part. Customers can rate how easy the repair was to complete and how long it took. We aggregate this data to provide a repair rating that allows customers to quickly determine the difficulty and time needed to perform their own repair.
