Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 452451. 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 1999-2003 BMW 540i, 1999-2001 BMW 740iL, and more, this direct-fit catalytic converter also interchanges with OE part 11 62 1 437 495. Avoid potential exhaust leaks by using the included gaskets to get a proper seal. This replacement part is designed to meet or exceed California Air Resource Board requirements, and has undergone additional testing to comply with CARB guidelines to allow for legal use in California and CARB restricted states, for the listed vehicles.

PERFECT FIX

Perfect fit for DIY oil filter change on 2021 BMW X-7. Good quality, well made, should outlast the vehicle.

I like the red. It does the intended job perhaps like others do.
Size: 32 mm, Color: Red
It's a socket. It does the job without any fail to report. I like that it's red so that I find it easily in my tool chest the next time I need it.
