MagnaFlow 2002-2003 福特 F-150 5.4L 加州等級 CARB 認證 直接安裝觸媒轉換器 4583753

Took about 90 minutes to bolt up in my driveway and the mandrel-bent tubing lined right up with the factory mounts. No check engine light since installation and the truck idles smooth again.

Welding looked clean and the O2 sensor bung was perfectly aligned on mine, no leaks at the flanges after a hundred miles. Glad I can finally pass smog without worrying about the check engine light flickering.

Bolt-on fit was dead-on for my 2003 F-150, and the mandrel-bent tubing looks like it'll outlast the truck. Check engine light stayed off through the first smog check, which is exactly what I needed from a CARB-compliant unit.
