Thomas ★★★★★

The mandrel-bent tubing is a nice touch—it fit right into place on my CT6 without any wrestling. Bolted up in about an hour and the CEL stayed off through a full tank of gas.

Joseph ★★★★★

I was a bit nervous about the check engine light, but this converter fit perfectly on my CT6 and the light stayed off. The corrosion resistance already seems solid, and the mandrel-bent tubing gave a clean install without any extra adapters needed.

Lily ★★★★★

The mandrel-bent tubing made installation a breeze on my CT6, and the corrosion-resistant finish gives me peace of mind for the long haul. Fits perfectly with no modifications needed, and the engine runs smoothly now.
