John G. ★★★★★

This converter bolted right up to my 2007 Lucerne without any modifications needed. The corrosion-resistant finish is a nice touch since I drive on salted winter roads. Check engine light has stayed off for the past 500 miles.

Thomas ★★★★★

The mandrel-bent tubing made installation straightforward, and it silenced that rattling exhaust noise I’ve been dealing with for months. No more worrying about the check engine light flickering on every time I hit the gas.

Adam ★★★★★

The check engine light went off immediately after installation, which is exactly what I needed. The direct-fit design lined up perfectly with the stock hangers, saving me a trip to the exhaust shop.
