Review on 🚗 MagnaFlow Manifold Catalytic Converter - Federal/EPA Compliant 49293: Stainless Steel, OEM Grade, 2.75in Piping, 19.125in Length, Pre-&-Post Converter O2 Sensor, OEM Replacement by Anthony Gupta

This is the 3rd The catalytic converter I bought is mine second magnaflow. The first Magnaflow had a varied design that cracked and splintered after about 6 months. However, this one has a header design that is much better for airflow and stability. The car was only a week away but I can see it will far outlive the others I've bought. Pros: Significant increase in fuel consumption compared to stock. Smooth acceleration. Passed the emissions test with flying colours. not a perfect fit, I had to make some adjustments - there is no bracket at the bottom, if you want you have to weld it on, which I highly recommend. All in all, this is a very good buy. I recommend it. Got rid of the annoying engine light that the 2005 Altima is notorious for. It was a power loss from my headers which I put in after two blown catalytic converters, but my stupid condition means I can't have headers. But this design is good. You will not regret it. I also completely replaced the exhaust. Including secondary converter. This is likely what contributed to such a huge increase in MPG. But the role itself played a huge role.
