Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 51374. With features including free-flowing mandrel-bent tubing and highly corrosion resistant, stainless steel construction, easily install this spun body converter yourself using the proper tools, no cutting or welding required. MagnaFlow's state-of-the-art metrology department uses the latest 3D scanning systems during research and development, so you can be confident that your new part will fit and function like the original equipment. By replicating the OE spun body design, the single laser fusion weld greatly reduces the possibility of a leak, and our compact, low-mass design also allows for greater thermal efficiency. Designed to fit the 2008-2011 BMW 528i, 2006-2007 BMW 530i, and more, this direct-fit catalytic converter also interchanges with OE parts 18 30 7 541 847, 18 30 7 541 849, among others. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation.

not tight enough
It did slip on my BMW M5 F90 oil filter — it wasn’t tight enough. I had to use a microfiber cloth to fill the gap and make it tighter in order to loosen the oil filter.

Works as promised
Size: 2-Pack
Great product! Highly recommend. My check engine light turned off quickly, probably less than 20 minutes after I added the bottle to my tank and started driving. I waited a week to write the review just to make sure the check engine light didn’t turn on again. Success!
