Overview:

Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 5491966. 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 to fit the 2007-2008 Hummer H3, 2007 Chevrolet Colorado, and additional vehicles. Avoid potential exhaust leaks by using the included gaskets to get a proper seal. This replacement part is designed to meet or exceed California Air Resource Board requirements, and has undergone additional testing to be certified by CARB for legal use in CA/CARB restricted states for the listed vehicles.

Definitely genuine pelts.
Size: 2' x 3' (Natural shape, Sheepksin, Oblong), Color: Ivory White
I like the color. Not too white, more of a natural shade. I ordered two, for each side of the bed. One is larger than the other which proves they are genuine pelts and I’m ok with it!!

Great small size rug
Size: 2' x 3' (Natural shape, Sheepksin, Oblong), Color: Ivory White
Size is great, I wanted to use as a throw on a leather ottoman and it fit great. It isn’t exactly the color I expected but it is a neutral cream. Soft and comfortable. Well made.
