MagnaFlow 2012-2015 Ford Focus 2.0L 加州等級 CARB 認證 直接安裝 歧管式觸媒轉換器 5531253

Was worried about the CARB compliance headache, but this bolted right up to my 2014 Focus and passed smog with no issues. The fit was spot-on and the check engine light stayed off after the first drive.

The mandrel-bent tubing made installation straight forward, and it's been about a month without that dreaded check engine light coming back on. Exhaust smells much cleaner too, which is exactly what I needed for the California smog test.

Three weeks in and the check engine light hasn't come back once, which is a huge relief after wrestling with the P0420 code for months. The direct-fit design meant I didn't have to fiddle with any extra pipes or brackets, and the welds look clean and solid.
