Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 49872. 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 2004-2009 Audi S4 and interchanges with OE parts 8E0 254 554 PX and 8E0 254 551 PX. Hardware is included to eliminate the hassle of working with corroded factory parts.

Nice Shirt, but not "Wrinkle Free."
Color: Blue, Size: Large, Color: Blue, Size: Large
I like the weight, feel and fit of the shirt, however it is NOT "Wrinkle Free." I put the shirt through the wash to see if that might fix the issue, but it's still wrinkled and I plan to return it. (Perhaps - if I ironed it - it would stay wrinkle free after that, but I have a closet full of truly wrinkle free shirts and pulling out the iron simply feels like too much effort.)

Not Wrinkle-Free at All — Very Misleading Description
Color: Orange-pink, Size: Medium
I specifically purchased this clothing item because it was advertised as having “Wrinkle-Free Fabric.” Unfortunately, the actual result was very disappointing. After washing and drying it according to the care instructions, the entire garment came out covered in wrinkles. There was absolutely no sign of any wrinkle-free or anti-wrinkle effect. Every wash still requires ironing, which seriously contradicts the product description. If you are buying this item because of the “Wrinkle-Free” claim, I would recommend thinking twice. The quality does not match the advertising at all.
