The 4-inch round body fits perfectly in my truck's exhaust tunnel, and the straight-through design gives a deep, aggressive tone without being too loud at highway speeds. I'm honestly impressed with how much smoother the engine feels now.

Bolted this on Saturday morning and the deep, mellow tone is exactly what I was hoping for—no droning on the highway. I can feel a nice bump in throttle response too, which matches the free-flowing design they mention.

The deep, mellow tone when I hit the gas is exactly what I was after, and the free-flowing design seems to have given my truck a bit more pep. It was a straightforward bolt-on job that took less than an hour.
