Isabella E. ★★★★★

The 5x8 oval fit perfectly under my truck and that signature exhaust note is exactly what I was after—deep and throaty without being obnoxious. You can really feel the dyno-proven performance difference when you hit the gas.

Henry ★★★★★

I was a little skeptical about the oval shape, but the straight-through design really opened up the exhaust flow on my Jeep. It has a deep, mellow tone without being obnoxiously loud on the highway. Very pleased with the upgrade.

Jason Y. ★★★★★

The sound is deep and aggressive right off the idle, and the straight-through design really lets the engine breathe. I was surprised how much cleaner the tone got after a few hundred miles, and it's still not obnoxious on the highway.
