### ⭐⭐⭐⭐⭐ High quality

### ⭐⭐⭐⭐⭐ Sound nice
*by P***L on September 6, 2026*

Good muffler

### ⭐⭐⭐⭐⭐ Drone Killer!
*by N***K on October 22, 2019*

I bought a used 2015 V6 Camarro that came with Flowmaster mufflers on the back. It sounded more like a souped up import than a muscle car and had a terrible drone right around 1700-2300 rpm a.k.a. highway cruising and wake the neighbors high idle. My wife was exhausted after a 1 hour drive and I got tired of setting off the car alarm in the little Honda that parks behind me. I added this muffled x pipe up stream and kept the Flowmasters in place. Nothing compares to the sound of a V8 with headers, but this unit took the raspy tuba out of the high range and gave it more of a growling idle. Definitely more "American" sounding. It stepped on that drone pretty good too. The obnoxious drone range pinched down to around 1900-2050 rpm and isn't as loud when it's in it. I still set of the Honda's alarm from time to time when he parks to close, but I took the wife on a 2 hour cruise through the mountains and she was happy with the reduction in noise. The car has a nice grunt when I step on it, but is much quieter in cruise, and if I use the paddle shifters to get further away from the droning range, it goes silent. I couldn't be happier with how this pipe balanced my car between daily driver and kept a good time when I want it.
