MagnaFlow 2004 Volvo S40 1.9L / 2004 Volvo V40 1.9L 加州等級 CARB合規 直接安裝 觸媒轉換器 441031

I was worried about fitting it myself, but the direct-fit design lined up perfectly with the old unit’s mounts. The check engine light stayed off after install, which is a huge relief.

The mandrel-bent tubing really made a difference in how easily everything lined up under the car, and the CARB compliance means I don't have to worry about smog checks here. Bolted on without any extra parts needed, and the check engine light hasn't come back since.

The install was straightforward on my 2004 S40, and the mandrel-bent tubing fit perfectly without any modifications. My check engine light went off immediately after replacement, and the exhaust note is surprisingly smooth for a direct-fit part.
