## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Sounds great on my 01 Mustang
  

*by G***. on Reviewed in the United States 🇺🇸 on March 28, 2021*

I've had this setup on my car for about 2 years now and still love the sound. The fit and finish are still holding up perfectly. No complaints what so ever. This exhaust sounds like a cherry bomb in the sense there is not a muffler with baffles, but its a deep, throaty sound. It just sounds healthy. All my friends, family and coworkers agree and say it sounds great. I think it sounds better than the more common Flowmaster 40 series every single Mustang has.
