Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 21-580. 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 2015-2016 Audi A3 Quattro and interchanges with OE part 5Q0 254 501 DX. Hardware is included to eliminate the hassle of working with corroded factory parts.

Cute soft and cuddly
So soft, cute and cuddly. The quality of softness and materials used are amazing. It’s light weight and fluffy but not thin. The size is perfect for cuddling. Not small sized. Gifted this to my mother for her birthday. She loves it says it’s so soft on her skin. Don’t imagine I would have an issue with washing or drying. Price was awesome and definitely would purchase again.
