MagnaFlow 2003-2004 福特 Expedition 4.6L HM Grade 聯邦/EPA 認證 直接安裝觸媒轉換器 24440

The mandrel-bent tubing made installation straightforward on my '04, and the corrosion-resistant finish gives me confidence for years of use. No more check engine light troubles since swapping this in.

Installed it on my 2004 Expedition and the check engine light stayed off through the first 200 miles, which is exactly what I wanted. The corrosion-resistant housing looks solid, and the mandrel-bent tubing made the alignment straightforward even with my rusty old mounts.

The mandrel-bent tubing flows so smoothly that my Expedition's throttle response feels noticeably crisper now. Four months in, the check engine light hasn't flickered once, and the welds still look as clean as the day I bolted it up.
