Love and hate this muffler

Good. I love and hate this silencer. I gave it five stars because it's great quality and probably the best muffler I've ever had and I've had a few on different vehicles in the past. However, it is a bit noisy for everyday use. Do this on a 5.3 Sierra cam that was freshly welded where the stock muffler was and the trailing spool removed for reference. In the future I will probably upgrade to a larger Magnaflow. It also hums fairly loudly around 15-1700 rpm, again if it were in a car I don't drive every day it would be fine.

Pros
  • Stable test results
Cons
  • Nothing here
