Catalytic Converter with Integrated Exhaust Manifold

California Manifold Catalytic Converter

Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 5551759. 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 specifically for the 2004-2006 BMW X3 and interchanges with OE parts 18 40 7 514 503 and 18 40 7 514 505, among others. 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 comply with CARB guidelines to allow for legal use in California and CARB restricted states, for the listed vehicles.

Legs seem decently thick. They could be a little sturdier. The paint has stayed with no chips or flakes. Color has not faded. It sits at the perfect height for a desk. Screws and hardware do the job. No welds to speak of, everything screws together. I’ve used these for a year and a half as a school desk and has held up well. I took a sheet of project board with stain and polyurethane as my top. Works excellent

Very sturdy legs!
Style: Zig Zag, Size: 28 inch, Style: Zig Zag, Size: 28 inch
The legs are very well built and good looking, however, the screws included for installation are only 9/16" long which is not nearly enough for table legs of this size. I installed the legs on a 30" x 83" live edge oak tabletop that is full 2" thick. I purchased 1 1/4" screws for the install making the table very solid.
