Scarlett ★★★★★

Had a check engine light that just wouldn't go away until I swapped the old converter for this one—been a month and it's stayed off. The fit was spot-on for my 4.7L Durango, and the corrosion-resistant shell gives me peace of mind during salty winters.

Aurora ★★★★★

The mandrel-bent tubing made the install much smoother than the stock replacement I tried before, and the check engine light has stayed off for a week now. Fit perfectly on my 4.7L Durango.

Timothy ★★★★★

Installed it in about an hour and a half, and the fit was spot-on with no extra cutting needed. The mandrel-bent tubing flows nicely, and the check engine light has stayed off through two weeks of city driving.
