Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 51644. 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 1998-2005 Volkswagen Passat, 1997-2005 Audi A4 Quattro, and more, this direct-fit catalytic converter also interchanges with OE parts 8E0 131 089 DX, 4B0 254 200 X, among others. Avoid potential exhaust leaks by using the included gaskets to get a proper seal.

Professional, functional, and cute!
Color: Pinkish Grey, Size: 14-Inch
I needed a backpack that looked professional and that wasn't massive. This fits my 15 inch laptop with room to spare. The back zipper portion is padded for extra laptop protection. I was surprised by the quality. It's my go-to bag for transporting my work stuff to and from the office.

Perfect Small-ish Business Bag
Color: Apricot, Size: 14-Inch
I have been on the search for a small business bag, that can go on. top of my luggage as well as look nice in the office and at meetings. That will still hold all of my things while keeping me organized. So what fits, I can put my 12.9" iPad, with case and Magic Keyboard in the spot for a laptop. I can also put my 8x10 spiral bound planner, a notebook, mouse, small cable case, pencil case, water bottle and purse pouch with all my essentials. So my water bottle does not fit inside the side bottle pockets, so I do have to put it inside the bag it's self, but that's a no issue. The shoulder straps seem sturdy enough and the color beige/cream looks nice with my neutral wardrobe. Overall I'm happy with the purchase. We'll see how it travels over the next year as I have quite a bit of traveling and work do to offsite this year. j

Stylish, High-Quality Backpack. A Great Upgrade from My Usual Black Bags!
Color: Pinkish Grey, Size: 14-Inch
I’m really impressed with this backpack. I usually stick to black bags, but I decided to try something different, and I’m so glad I did. The color is beautiful—unique without being too loud—and adds a nice pop. The quality of the material feels top-notch. It’s sturdy yet lightweight, and the stitching and zippers seem very durable. Overall, this backpack feels well thought out in both design and function. Highly recommend if you’re looking for something professional, stylish, and practical.
