MagnaFlow 2001-2002 日產 Frontier 3.3L 加州等級 CARB 認證 直接安裝歧管觸媒轉換器 447193

The mandrel-bent tubing on this cat is clearly high quality, and it bolted right up to my 2001 Frontier without any modifications. My check engine light hasn't flickered once since installation, which is exactly what I needed for California smog.

Check engine light stayed off through two smog checks since I put it in, so the CARB compliance is legit. The direct-fit design lined up with the factory mounts perfectly, no wrestling or extra parts needed.

My gas mileage actually improved a bit after installing this, and the mandrel-bent tubing made the old pipe alignment perfect. Check engine light stayed off through the smog check, which was my main worry.
