Richard W. ★★★★★

I was a little worried about getting a check engine light after swapping out the old one, but this converter fit perfectly and the light never came on since. The mandrel-bent tubing is nicely corrosion-resistant, too.

Ava C. ★★★★★

The mandrel-bent tubing made installation surprisingly straightforward, and the welds look clean and solid. Bolted right up to my truck's existing exhaust without any alignment headaches. Check engine light stayed off as promised, which was my main concern.

Edward K. ★★★★★

Installed this on my '04 Camry and the mandrel-bent tubing made for a perfect alignment with the existing pipes, no modifications needed. It's been a few weeks and the car runs cleanly with no check engine light, just a solid, quiet exhaust tone.
