George ★★★★★

The check engine light finally stayed off after swapping in this converter; the mandrel-bent tubing made installation straightforward on my Lincoln LS. Fits like factory, and the exhaust note didn't get raspy like I worried it might. Exactly what I needed for passing emissions.

Avery W. ★★★★★

Bolted right up to my 2005 Thunderbird without any modification needed, and the check engine light stayed off after the first drive. The mandrel-bent tubing seems solid and the fitment was spot-on.

Avery ★★★★★

I was worried about rust, but the stainless steel construction on this converter looks solid and the welds are clean. Bolted right up to my Thunderbird without any modification needed. Check engine light stayed off after the first drive, which was a relief.
