Alexander ★★★★★

That deep, aggressive rumble at idle is exactly what my Mustang needed, and the sound just builds beautifully as you accelerate. Really woke the car up without being obnoxious on the highway.

Benjamin ★★★★★

The deep rumble at idle is exactly what I wanted for my '99 GT—it sounds mean without being obnoxious on the highway. The polished tips really pop against the rear bumper, and the install only took a couple hours with basic tools.

David ★★★★★

Installed this on my '01 GT and the aggressive, deep resonance is exactly what I was hoping for. The cat-back system bolted up without any major issues, though I'd recommend having a second set of hands for the rear hangers. The sound at wide-open throttle is just nasty in the best way.
