Leo ★★★★★

I swapped out the old clogged unit on my Xterra and this bolted right up without any modifications. The mandrel-bent tubing made for a clean install, and the check engine light has stayed off ever since.

Eli ★★★★★

My 2003 Frontier was running rough and throwing a check engine light, but this converter fit perfectly out of the box and the corrosion-resistant coating looks like it’ll last years. Took about an hour to install with basic tools, and the engine light shut off after a short drive.

Brian ★★★★★

The mandrel-bent tubing made routing this converter under my Xterra a breeze, and the welds look like they’ll outlast the truck. Bolted right up to the factory flanges without any modification needed, and the check engine light stayed off after the first drive.
