    Absolutely music to my ears for the money!!
  

*by R***E on Reviewed in the United States on 24 October 2023*

This is absolutely hands down the best sounding Axle-Back exhaust system available for a Mustang. Then again, it’s Roush!!  It is what I would expect.

### ⭐⭐⭐⭐ 







  
  
    Louder that thought
  

*by K***. on Reviewed in the United States on 17 November 2019*

Seems to be a lot louder than in their video. Look good, and the Shelby is putting out 620 Hp, without much effort.
