    Rated 5 out of 5 by from Just right! I first had a Flowmaster 40 cat back system, but the drone was terrible and the tone was too throaty for my truck. I ordered this and replaced the Flowmaster. It is perfect! Very little drone, it is still loud, but it's not annoying it's a very beautiful rumble. Then at high resolutions it sounds like a fine tuned racing machine. I love it!
