James ★★★★★

Took about an hour and a half to swap out my old converter for this direct-fit model, and the mandrel-bent tubing lines up perfectly with the factory exhaust. The check engine light turned off after the first drive and hasn't come back in the week since.

Grace ★★★★★

Installed this on my 2004 Liberty last weekend, and the mandrel-bent tubing made for a much cleaner fit than the stock section I replaced. Check engine light stayed off after the first drive cycle, exactly what I needed.

Eli ★★★★★

After two years with the old one throwing a P0420 code, this unit finally silenced that check engine light. The mandrel-bent tubing feels noticeably smoother than the factory pipe I took off.
