Overview:

Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 4451211. 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 2003-2006 Chevrolet Express 1500, 2003-2006 GMC Savana 1500, 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.

The shelves sag away from the wall overtime
Color: White, Number Of Shelves: 2, Size: 15.7in, Color: White, Number Of Shelves: 2, Size: 15.7in
Although the wood quality and finish of the shelf are clean and well-made, the main issue is that the shelves begin to sag over time while holding around 10 pounds, even though the product listing claims they can support up to 20 pounds. They may perform better on a brick wall, but on drywall you should be cautious. To fix the problem, I had to purchase floating shelf brackets for support, which solved the sagging issue. However, this defeats the purpose of the “floating” aesthetic. Since the shelf is in my bedroom, I can overlook it, but I personally wouldn’t install these in a common area if I wanted a clean floating look.

Looks nice, easy to install
Color: Rustic Brown, Number Of Shelves: 2, Size: 22in
This shelf is lightweight, looks nice, and was easy to install. It comes with a little level to help you install it properly. There are plenty of mounting holes to choose from, so it is easy to screw it directly into a stud, or to just use holes that are convenient for you. It comes with a plethora of mounting hardware. I mounted mine a bit high up and chose to mount it upside down so that I wouldn't see the three screws that hold the shelf to the mounting bracket.
