Customer Reviews (4.8 / 5 · 5 reviews)

Natalie ★★★★★

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.

Sophia E. ★★★★★

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.

Aurora C. ★★★★★

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.
