Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 51437. 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 253 011 QX.

Charlie was better
Color: Ivy Green
The zipper, which is why I bought it, doesn't work well, gets stuck and damages bills. I used a Charlie before, and although it was more compact, it fit more cards and was generally more convenient.

The best of the basics
Color: Ivy Green
Simple and on point. Minimalistic. One side for cash, folded in half. Other side 3 slots can comfortably fit 4 cards: ID / bank & or credit card / costco card. Any more than 4 gets a little harder to pull out. But dont worry, thats what the zipper pocket is for. Maybe just a few more tho, like health insurance cards. For just the basics.

Perfect for a minimalist
Color: Ivy Green
My husband had this exact wallet for 8 years. It was still functional and used daily. I got him this replacement and he was beyond excited. Said that it was his favorite Christmas gift lol. The durability and function of this minimalist wallet is unmatched. Love the color too!
