Madison ★★★★★

Bolt holes lined up perfectly with the factory flanges on my 2010 Lucerne, and the mandrel-bent tubing made installation straightforward. Check engine light has stayed off through about 500 miles so far.

Hazel T. ★★★★★

Swapped this in over the weekend and the check engine light stayed off through my first 200 miles—the direct-fit design made bolting it up way easier than I expected. The mandrel-bent tubing feels solid, and it’s nice knowing it’s EPA compliant so I don’t have to worry about emissions testing.

Aurora C. ★★★★★

My old Lucerne’s engine light was driving me crazy, but this converter fit perfectly and the check engine light is finally off. The corrosion-resistant tubing is a big plus since I live in the rust belt.
