MagnaFlow California Grade CARB Compliant Universal Catalytic Converter 441174

I was getting intermittent check engine lights before, but after swapping this in, it's been solid for two weeks now. The universal fit made installation straightforward with just basic hand tools.

Bolt pattern lined up perfectly on my '03 F-150, and the stainless steel shell feels much sturdier than the old one I pulled off. Check engine light stayed off after installation, which is exactly what I needed to pass smog here in California.

Took a chance on this universal converter for my old project car, and the stainless steel casing looks like it'll outlast the rest of the exhaust. It bolted up with only minor adjustments, and the check engine light stayed off after the install.
