MagnaFlow Premium Metallic Federal / EPA Compliant Universal Catalytic Converter 69011

Installed this on my '04 Silverado and the CEL stayed off just as promised. The universal fit required a bit of welding, but the metallic substrate seems well-built for the price.

After replacing my old clogged unit, this MagnaFlow converter fit perfectly despite the universal design and my check engine light has stayed off for two months now. The metallic substrate seems to heat up fast and pass the sniffer test at inspection.

My check engine light finally stayed off after swapping this in, and the universal fit saved me from hunting for an exact match. The metallic core seems solid so far, and installation took me about an hour with basic tools.
