As a professional technician I see many different mufflers coming to the store, usually Flowmaster or Magnaflow. Having bought several mufflers from each brand and then tried this one, I will never buy a more expensive muffler again. The quality of the welds looks great, the cost is 8 times less than the cost of threading, and it sounds great! No drone has a comfortable drone when idling and when you sit on it it sounds nice.
