Customer Reviews (4.8 / 5 · 5 reviews)

Emily P. ★★★★★

The deep, mellow tone at idle is exactly what I was hoping for, and the straight-through design definitely wakes up the mid-range pull without being obnoxious on the highway. Fitment was spot-on with the factory hangers, took me about an hour in the driveway.

Ava H. ★★★★★

Installed this on my truck last weekend and the tone is deep without being obnoxious inside the cab. The oval shape fit perfectly into the existing hangers with no extra modifications needed. Noticed a slight bump in low-end torque just from swapping out the old muffler.

Ellie ★★★★★

The difference in sound was immediately noticeable after installation, and the oval shape fits perfectly in the tight space under my truck. Install was straightforward and it gives a deep, aggressive tone without being obnoxious on the highway.
