Overview:

Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 458011. 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 S10 and 2003 GMC Sonoma. 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.

Nice display shelves
Color: Black
These shelves are really easy to install unless you just don’t have any kind of skill at all with putting it where you want it and making sure it’s level and marking you anchor points. Shelves themselves look good and are really sturdy for small display items. Not much work at all to put together.

Not squared shelves
Color: Rustic Wood
I thought these shelves would be squared but they are actually rounded at the corner making them a but awkward to hang especially if your walls aren't perfectly squared. They look pretty once hung but they are quite hard to hang if you go by the instructions. I would not buy these again.
