Review on Borla 11750 Rear Section 'S-Type' System Exhaust: Unleash Optimal Performance by Jimmy Scaturro

I was very pleased with the muscle car sound of these mufflers. Very little or no hum. Before installing Borlas I was using Flowmasters. Even though the Flowmasters hum at certain speeds, I sometimes still miss the sound of the Flowmasters idling. I guess it's normal for a Mustang owner to be dying to try something different after years of using one brand of muffler lol. I am very happy with Borla.
