Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 21-171. 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. This direct-fit catalytic converter is designed specifically for the 2009-2016 BMW Z4 and interchanges with OE part 18 30 7 647 049. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation.

Seems like an excellent purchase so far!
So far so good! And we really appreciated the little hair cutting tool for the roller—nice touch. We've replaced one bag, one brush head, and one filter using this bargain kit so far, nothing much to complain about. It's not quite OEM quality but it's very likely going to work well enough. We expect to go through one kit like this per year. Be aware that the rotating brush head replacement (the small round head ones, not the big rollers), have a little philips head screw that you have to remove. This was kind of hard to get off at first. We haven't used one of the replacement rollers yet, expect that we'll go through about two a year with our C10 at the current rate of wear.

Nice extras
This kit is great to keep my vacuum running! It’s nice to replace the brushed when they get tangled with pet hair.
