Eli P. ★★★★★

My old Buick had been throwing P0420 for months, but the mandrel-bent tubing on this converter made installation a breeze and the check engine light finally stayed off. Even with the 3.4L, the engine feels like it breathes better now.

George ★★★★★

My '05 Aztek's check engine light had been on for months, but this converter finally turned it off and has stayed off through a week of driving. The CARB compliance was a must for California smog, and the direct-fit design made swapping the old one out pretty straightforward.

Lily X. ★★★★★

The mandrel-bent tubing made installation a breeze—everything lined up perfectly with the factory mounts. Truck passed the smog check with the CARB sticker visible, and the check engine light hasn’t flickered once in three weeks of daily driving.
