Customer Reviews (4.4 / 5 · 5 reviews)

Scarlett ★★★★★

The oval shape made it a breeze to fit under my Silverado without any clearance issues, and the sound at idle is a nice low rumble that doesn't drone on the highway.

Penelope ★★★★★

Dropped it on my '05 Mustang GT and the sound is exactly what I was after—deep and aggressive without being obnoxious on the highway. The straight-through design really woke up the mid-range, and the oval shape was a perfect fit in the stock location.

Victoria ★★★★☆

I was a bit worried about how loud it would be, but the straight-through design gives a deep tone without being obnoxious. The oval 5x11 inch body fit perfectly into the factory hanger location with no extra fab work.
