MagnaFlow California Grade CARB 認證通用觸媒轉換器 454305

The O2 sensor bung was already welded in, which saved me a lot of hassle during installation. It fit my truck’s exhaust layout perfectly and the check engine light has stayed off ever since.

Welded this in last weekend to replace my old failing unit, and the stainless steel construction already feels way more solid than what I pulled off. The check engine light turned off right after the first drive cycle, which was a huge relief.

Had my check engine light on for weeks until I swapped in this unit, and it cleared right up. The stainless steel construction feels solid and should hold up well here in the rust belt.
