Performance and sound at a great price.

Delta 50 made exactly as described. The "hum" we all experienced at cruising speed has almost been eliminated. My friends tell me my car sounds better and smoother than my previous mufflers. Another great Flowmaster product.

Pros
  • Moderate sound
Cons
  • Not sure

Sounds right to me.

The third car I switched to Flowmasters. Tahoe and two Taurus SHOs. The sound is excellent, not too loud inside and a pleasant rumble outside. My wife says I'm a kid at heart. and she's right

Pros
  • Improved engine power, torque and efficiency
Cons
  • ---

Jeep Wrangler 8 was perfect. Almost standard sound, but gas pedal sound

The sound of the 3.8 Jeep Wrangler was perfect. Almost serial sound, but deep gas sound. The Flowmaster's dual exhaust was so stifling and annoying that I was fine when I switched to it. Very disappointed, only 8 months old and looks the same.

Pros
  • Moderate sound
Cons
  • Secret

Great sound without a drone.

Great sound with no hum. Installed on Wrangler 2015 2-door. This muffler is half the size of the original, making it much lighter. In contrast to the OEM muffler, it breaks in well. It emits a pleasant deep tone when idling up to 1500 rpm and when decelerating. At cruising speed there is no annoying hum, which I am happy to report on. This is exactly what I was hoping for.

Pros
  • Easy installation
Cons
  • Useless features
