Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 51965. 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 2004-2006 Audi A8 Quattro and interchanges with OE parts 4E0 254 501 AX and 4E0 254 501 X. Hardware is included to eliminate the hassle of working with corroded factory parts.

Love the look, but Narrow
Size: 10, Color: Marine Blue/Woodbury/Ivory
What is for my son-in-law, he loves them, but had to switch them out twice because they run very narrow. He doesn’t have a wide foot at all so be careful when you purchase. Other than that they are a good looking shoe and he really likes them.

Awesome value shoes
Size: 11.5, Color: Ivory/White/British Tan, Size: 11.5, Color: Ivory/White/British Tan
These white Cole Haan shoes are just what I hoped for, the color is a perfect off-white, somewhere between cream and pure white, which gives them a more refined look. The quality feels excellent, they’re very comfortable right out of the box, and the laces feel durable and well-made. They fit true to size with no issues. Based on this experience, I’ll definitely be buying more from this brand in the future especially at this price point.

Look great for dress up up casual
Size: 13, Color: Black Leather/Optic White
I wear them every day for work. They are comfortable and light. I will say I was frustrated with the crease in the top that started the first time I wore them but other than that they are a great pair of shoes.
