Review on 🔊 Vibrant Performance 1047 High-Performance Muffler by Damon Murray

I put this on the back of my Fiesta ST MBRP 409 stainless exhaust to tone it down a bit. The muffled "tractor" sound when starting off is completely eliminated and the car is easily half as loud as before (3 dB attenuation). All of the creaking is gone now, but there's still a deep bass "purr" component to the sound. It's even louder on the highway between 2800 and 3500 rpm, but it doesn't have the deafening hum it used to have. Now I can talk to other passengers in the car while driving and my Bluetooth audio doesn't mute the other end of the call because it detects loud exhaust noise when I'm talking.
