### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Replacement for my OEM Generac Muffler
  

*by C***T on Reviewed in the United States on June 20, 2024*

The Onan muffler is a little larger diameter and a little longer than my original Generac muffler. It's made a little better than the OEM Generac. Sound seems to be about the same as the OEM. It was a good price and shipped fast.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Glad I found this!
  

*by S***  on Reviewed in the United States on February 25, 2024*

So much better with this on, instead of a long pipe running up to the front of the right behind the driver's seat, gassing me out if I opened the window! just redirect the pipe to the rear, into the muffler and out next to the big exhaust pipe.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Major reduction in noise level for my generator.

     It is excellent quality, and made my project of reducing noise from generator substantially, very successful. Reduces tail pipe noise from 72 to 62 dB. Although I had to modify to fit properly as it was not intended for this application it was a fantastic addition to gen set.
