Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 51438. 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 2002-2004 Audi A6 Quattro and 2002-2004 Audi A6, this direct-fit catalytic converter also interchanges with OE part 4B0 253 012 QX.

The Editorial Company Wolters Kluwer and VitalSource
Format: Hardcover
I was looking forward to my textbook which arrived in great condition. I needed to activate the ebook and it was a disaster. I could not redeem my code for unclear reasons, I called the number in the textbook which took me to an India location, answered by someone who could not enter my e-mail correctly, and ended having to create a ticket. I was told I had to wait 24-48 hours to resolve the issue. I called the Editorial company and they were not able to help stating it was not their issue. It has been very frustrating. I bought 6 medical books from Elsevier, all of them redeemed as I received them, immediately activated. No hassles at all. Big difference in services between editorial companies and digital resources

DO NOT PURCHASE THIS BOOK.
Format: Paperback, Format: Paperback
If I could give zero stars, I would. Do not purchase if you intend to use the Access Code. I was very careful to scratch off the Access code, but you can see it was still unreadable. I went to the website and submitted a ticket. One option for a reason to submit a ticket is 'unreadable access code", so they know this is a problem. They ask for a photo of the code and a receipt of purchase. I sent both. Then they asked for proof that the book was purchased NEW. This was not noted on the Amazon invoice. I was instructed to reach out to the vendor for the additional info. Or I could spend more money on another access code. There are other study options available.
