Customer Reviews (5.0 / 5 · 5 reviews)

Lily ★★★★★

The sound is exactly what I wanted for my Mustang—deep and aggressive without being obnoxious on the highway. It really wakes up the 4.6L engine, and the stainless steel construction gives me confidence it'll last.

Grace B. ★★★★★

Installation took a couple hours in the driveway, but that deep, aggressive rumble at idle is exactly what my GT needed. The stainless steel tips and polished look really clean up the rear end nicely.

Jacob ★★★★★

Mid-range punch is where this system really shines—the resonance under hard acceleration is unmistakable, but it settles into a clean idle that doesn't drone on the highway. The cat-back install was straightforward, and the stainless tips line up perfectly with the bumper cutouts.
