Installed it on my truck and the low rumble at idle is perfect, not too loud but you know it's there. The oval shape fit neatly into the stock hangers with minimal modification.

Bolted this onto my truck and the sound is exactly what I was hoping for—deep and aggressive without being obnoxious. The straight-through design really opened up the flow, and I felt a noticeable difference in throttle response. Install was straightforward with the 4-inch oval fitment.
