Customer Reviews (5.0 / 5 · 5 reviews)

Madison X. ★★★★★

Install was straightforward on my B8 S4, and the sound is exactly what I was hoping for—deep and aggressive under throttle but settles into a refined hum on the highway. The 5-inch polished tips fill the rear valance perfectly without sticking out too far.

Evelyn V. ★★★★★

I was worried the drone would be annoying on the highway, but at cruising speeds it's almost silent—just a deep, refined tone that makes the S4 feel alive. The polished tips look fantastic against the rear diffuser, too.

Andrew O. ★★★★★

The fit on my 2014 S4 was spot-on, and the deep tone at idle is exactly what I wanted without being obnoxious. Definitely wakes up the car's personality compared to stock.
