Customer Reviews (4.8 / 5 · 5 reviews)

Jacob ★★★★★

Installed this on my F-150 and the straight-through design really woke up the low-end torque. The 5x8 oval fits perfectly in the stock location without any modifications.

Penelope F. ★★★★★

The oval shape clears my truck’s frame rails perfectly, and the straight-through design gave me a deeper tone without any drone on the highway.

Eli A. ★★★★★

I was surprised at how easy this muffler was to bolt up—took me less than an hour in my driveway. The straight-through design really opens up the exhaust flow, and you can feel it in the midrange.
