Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 21-915. 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 2016-2017 Cadillac CT6. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation.

Nice tire sealant.
Size: 32 oz
This seems to work very well. I will say that it seems to be pretty important to move the wheel around as soon as you can to distribute the product within the tire. I was held up for a few minutes and the Liqui tube seemed to start to set up in one spot and made the tire out of balance so I had to work quick to get it to distribute to the other parts of the tire. It seems to have worked though and so far the tires are holding air very well. I will be interested to see if it lasts for a long time but so far so good.
