Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 21-172. 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 7 647 051. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation.

Very nice shirt for the price
Very nice quality shirt at a great price. Bought it for my son for hoco but he ended up not going so I had to return it. The fit was very comfortable and true to size. It came with cuff links. I would definitely buy it again if we need a dressy shirt for an occasion.

Runs tight
It's a little tight for a 2XL even with the stretch. Nice color, kind of stretchy, nice material, didn't have many wrinkles at all, soft, but was pretty tight.
