I love the sound, my torque at low revs is better and I no longer have hesitations when accelerating in my Tundra 07. It wasn't easy to install in a garage, so 100% bring it to a buy silencer because it is cheaper and less headache. The drone appears only at highway speeds at 1750-2000 rpm, and at 2500 rpm the noise disappears. This may be because I removed the last resonator after the silencer, so this can just be my situation.
