Overview:

Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 4451208. 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 2003 Chevrolet Venture, 2003 Buick Rendezvous, and additional vehicles. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation. 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.

Hard to assemble
Color: Grey
This is extremely hard to put together, but once its together it is pretty good. You will need to secure it to something. It falls over.

Great invention
Color: White
Second pack of these and I love them. I used them mostly for computer cables in my home office and my work office so I did not constantly have to go digging for laptop power cords and adapters. They have a strong adhesive that is very durable, the installation was super easy, super functional and overall great value for the money. These would be versatile as well if you wanted to use them for say phone charging cables or similar cords that seem to always fall behind a shelf or something similar.
