I did a good bit of comparison over the past few months. Videos, muffler shops, standing on street corners, truck meets, etc etc.
The Carven is a deeper, throaty growl. Doesn't have that higher pitched BAP BAP BAP of some mufflers on take off or deceleration. It quite stealthy for a muffler, until you jump on it, then it growls like a Hemi should.
