Customer Reviews (4.8 / 5 · 5 reviews)

Scarlett ★★★★★

Bolted right up to my '25 GT without any modification needed, and the deep tone at idle is exactly what I was hoping for. The mandrel-bent 2.5-inch piping really opens it up without being obnoxious on the highway.

Ava ★★★★★

The mandrel-bent 2.5-inch tubing really opens up the throttle response on my Mustang, and the direct-fit design meant I didn't have to mess with any adapters. It's got that deep, throaty bark at idle without being obnoxious inside the cabin.

Madison ★★★★★

Installation was straightforward since it's a direct-fit kit, no cutting or welding needed. The tone is deep and aggressive without being obnoxiously loud, exactly what I wanted. Noticeably better throttle response compared to the stock setup.
