James V. ★★★★★

The weight difference is shocking when you first pick it up—feels like a toy compared to the stock muffler. Bolted right on in about an hour with no fitment headaches, and the blue titanium hue shifts color beautifully in the sun. The single exit tone is deep and aggressive without being obnoxious o

Ellie T. ★★★★★

The blue titanium finish looks even better in person than online, and it's so light I almost thought the box was empty. After a week of driving, the sound is deeper and more aggressive than stock without being obnoxious on the highway.

Timothy W. ★★★★★

Bolted it on in about an hour with zero fuss, and the weight savings are immediately obvious when you lift it out of the box. The full blue titanium shifts color in the sun, but the real kicker is how the single exit wakes up the rumble without being obnoxious on the highway.
