Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 21-504. 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 2015-2017 Mercedes-Benz C300, 2016-2017 Mercedes-Benz GLC300, and more, this direct-fit catalytic converter also interchanges with OE part 274 140 18 08.

Nice Coat, But Could Better
Size: Medium, Color: Black
I like this coat overall. It fits really well, nicely tapered, and a good weight, but the fabric has a sheen to it, very noticeable in brighter light, which I'm not crazy about. It doesn't have any inner breast pockets, and I don't feel secure putting my phone in the side pockets. I did get lots of positive comments from friends.

Great style chose for any occasion
Size: Medium, Color: Black
Genuinely the perfect fit and great for the style I prefer. Great material and thick to keep you warm but not to hot. Black is deep and adds that depth that I am looking for

The description states 100% cotton, but it is actually 100% polyester. I don't know what I was counting on... Returning
