Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 52925. 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 BMW M4 and 2015 BMW M3, this direct-fit catalytic converter also interchanges with OE part 18 30 7 851 178. Hardware is included to eliminate the hassle of working with corroded factory parts.

Really nice shoes
Size: 9, Color: Black Polished Full Grain
My husband enjoys wearing these shoes. Very classy looking. They fit well. They arrived quickly. He liked them so much he ordered another pair in a different color which have worked out just as well.

Poor quality control - maybe outlet store leftovers
Size: 11.5, Color: Burgundy Polished Full Grain
The two shoes were not the same size. They were both labeled 11 1/2 but one shoe was larger than the other and the fit was poor. I returned the first pair and ordered a replacement. This time the shoes were close to the same size but too loose and the left one has sewing issues. I've bought Johnston & Murphy for years because of the quality. These were to replace an existing pair of burgundy penny loafers that have finally worn out (even after several heal/sole replacements). That is the expected quality. I suspect Nashville Shoe Warehouse may be handling shoes that didn't measure up for the quality; more like an outlet mall than getting the J&M quality I've come to expect. Update: went to Johnston & Murphy site to buy "direct" from the manufacturer. There were several recent reviews where the shoes were long and didn't fit properly. Genesco - please step up the manufacture / crafting of these classic shoes to the level of quality they used to have.

I usually wear 11.5's, but I buy 1/2 size smaller to accommodate for stretch. Leather relaxes.
Size: 11, Color: Burgundy Polished Full Grain
5 STARS: These shoes are awesome. I keep coming back for more. I have major foot problems, have tried all kinds of shoes, orthotics, and inserts... but believe it or not, these shoes work better than any of that stuff. I wear them daily. I buy lots of them, for home, for church, and I'm getting my first pair of J&M boots today, for winters in Indiana... Brrrr

Way too narrow
Size: 9.5 Wide, Color: Burgundy Polished Full Grain
I ordered a wide in this shoe, but it was still way too narrow. I had to return them. Otherwise, it looked like a nice quality shoe.
