Review on ๐Ÿ”Š Flowmaster 9530560 3 In/O 3 C 50 Series HD Muffler: Superior Exhaust Performance and Quality by Vivek Allen

Revainrating 4 out of 5

Sounds great for my taste.

Sounds great. Enough grunt at idle and excellent sound when accelerating. I left the rear resonator on so it doesn't get too loud. The truck now sounds like a truck. Update: Maybe this year they'll add a Flowmaster chamber resonator in front of the muffler and remove the OEM resonator next to the exhaust pipe. Flowmaster suggests their resonator helps a lot more than the factory installed one. I can still hear the 1500rpm hum in the MDS and it's annoying. Just use the shift buttons to prevent switching to 4 cylinder mode.

Pros
  • Inspires confidence
