Ryan ★★★★★

I wasn't sure how much difference a muffler swap would make, but this straight-through design really woke up the throttle response on my truck. The perforated core gives it that deep exhaust note without being annoyingly loud at highway speeds.

Joseph ★★★★★

The 4-inch oval body fit perfectly into the tight space under my car, and the stainless steel finish already looks great after a few days. It has that deep, mellow tone at idle but really sings when you get on the throttle.

John R. ★★★★★

Installed this on my truck last weekend and the sound is exactly what I was hoping for—deep and aggressive without being obnoxious on the highway. The straight-through design really wakes up the throttle response, and the welds look clean and solid.
