Lily K. ★★★★★

Installed this on my truck last weekend and the sound is exactly what I was hoping for—deep but not obnoxious. The 5x8 oval shape fit nicely in the stock location with only minor adjustments.

Ella U. ★★★★★

I was hesitant at first, but the sound from this straight-through muffler is exactly the deep, aggressive rumble I was after—and the offset/dual layout made it a perfect fit under my truck.

Natalie L. ★★★★★

The offset/dual design made installation a breeze on my truck, and the sound is deep without being obnoxious on the highway. Feels like I picked up some throttle response too.
