Samuel ★★★★★

Installed this on my '14 Grand Cherokee SRT and the check engine light has stayed off for over a month now. The mandrel-bent tubing definitely makes for a smooth fit under the chassis.

William ★★★★★

Bolt holes lined up perfectly with the factory mounts on my 2014 Grand Cherokee, saving me a trip to the exhaust shop. The check engine light hasn't come back on since installation.

Richard ★★★★★

The mandrel-bent tubing made installation straightforward, and the welds look clean and solid. My Jeep's idle smoothed out noticeably after swapping this in, and it's been running great for a few hundred miles now.
