MagnaFlow 2002-2006 日產 Sentra 2.5L 加州等級 CARB 合規 直接安裝觸媒轉換器 457014

Installed this on my 2005 Sentra last weekend and the check engine light finally stayed off after weeks of annoyance. The direct-fit design made the swap pretty straightforward even for my first time under the car. Feels solid and the exhaust note is clean without being loud.

The mandrel-bent tubing gave it a smooth, free-flowing feel that my old clogged converter lacked. Check engine light stayed off after installation, and it passed smog with no issues. Fit was snug under the Sentra without needing extra modifications.

Bolt pattern lined up perfectly with the factory mounts, so the whole swap took barely an hour. Two weeks in and the CEL hasn't come back once, which is a huge relief for passing smog here in California. The welds and heat shields look solid, too.
