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 2000-2004 Audi A6 Quattro and 2002-2003 Audi S6, this direct-fit catalytic converter also interchanges with OE parts 4B3 253 057 BX, 4B3 254 500 GX, among others.

Cashmere but far too thin
Color: Dark Navy, Size: One Size, Color: Dark Navy, Size: One Size
The beanie feels soft and genuinely made of cashmere, but the fabric is surprisingly thin — almost transparent when held to the light. It lacks the warmth and structure you’d normally expect from a cashmere item. The design and packaging are pleasant, but the overall impression is disappointing. It’s comfortable to touch yet too delicate to provide real protection against the cold.

Cool hat.
Color: Dark Navy, Size: One Size
This is a nice little hat. Even though it’s really thin, it does seem to keep my head warm. Really haven’t tried it out in the wind yet. But saying that you could put another hat on top of it.

Soft and durable!
I bought this for my husband as a christmas gift and so far it’s been great quality! He works outside and I wanted to get something warm and soft for the winter. It’s been washed (and air dried) 3-4 times in the last couple of months and it’s held up great!! Such good quality for the price. He says it’s very soft and warm and prefers it over itchy wool.
