MagnaFlow HM Grade 聯邦/EPA 合規 通用型觸媒轉換器 99185HM

Installed this on my Chevy Silverado yesterday and it fit perfectly with a little trimming. The check engine light stayed off after the first drive, which was the main goal. Feels solidly built for the price.

Welded it in on my old F-150 and the check engine light stayed off, which was a relief. The stainless steel body feels solid and the universal fit was close enough with minor adjustments.

The universal design actually made installation easier than I expected on my truck, and the check engine light has stayed off for the past two weeks. It's doing its job, though the included hardware felt a bit cheap.
