The sound is a real highlight. It delivers a smooth, deep tone that’s noticeable but not overwhelming.
It turns heads at stoplights, and the growl when you hit the gas makes the drive more fun. I also appreciated that it didn’t produce any annoying drone at highway speeds, which can spoil the experience with some other aftermarket mufflers.
