### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Awesome sound
  

*by J***R on Reviewed in the United States on October 24, 2022*

Great product, great value and sounds amazing on a 2009 Chevy with 6.0 liter LS motor. Dual outlet made for a desirable sound and still not obnoxious inside cab.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    sounds quiet just like I like it.
  

*by J***D on Reviewed in the United States on October 14, 2013*

if your looking for a fair priced replacement muffler for Chevy 6.0l that isn't gonna cost 500 dollars then this is it.  Some moron had hacked off the stock muffler and tried to get glass packs to work in its place and it sounded like crap, but the truck was in good shape so I bought it. Long story short the stock muffler was long gone so this is what I bought as a solution and its working really good.  It does have this nice low rumble that makes it sound just a tad bit perkier than the other 6.0's in my area.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Just Right for my 5.0 F150
  

*by B***N on Reviewed in the United States on August 8, 2018*

I wanted a deeper rumble and a little more volume than the stock exhaust on my F150. It was a bit louder than I expected but after driving with it for a week, I've gotten used to my truck sounding like a truck should sound. It has a nice balance, good tone when you hit the gas but not obnoxious. It sounds great accelerating, crusing 45-60 it quiets down to almost nothing. Anything above 70mph you can hear it in the background with the radio off, but with the radio or a conversation you can't hear it.
