Overview:

Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 4551404. 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 2003-2004 Toyota Tundra. 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.

It’s ridiculous…
Size: King (Pack of 2), Style: Medium, Configuration: Hometextile
When I got these pillows I was a little disappointed that they appeared to be a little lumpy. I fluffed and let them rest for a couple of days to see if they’d poof up. Finally figured this was as good as they were going to get. First night sleeping with them…my life has changed! I typically like a lot of pillows. I’m usually a restless sleeper. I fell asleep quickly and slept through the night for the first time since I can remember. No aches and pains as usual. It’s ridiculous that a couple of pillows could have made such a difference in my quality of sleep. Who knew?! I’ll buy these for every bed in the house.

Do not buy, I recommend looking for something else
Size: King (Pack of 2), Style: Medium, Configuration: Hometextile
I don't like the quality of those pillows. They don't have any support, super flat, it's like just using the pillow sheet without the pillow. I honestly don't get why this could even be a product. Amazon Basics brand is veryh nice but this one was a very bad one. I usually go with anything but this was worst than cheap airbnb pillows.

Great
Size: King (Pack of 2), Style: Medium, Configuration: Hometextile
The medium density support is exactly as advertised and provides more support and firmness. The pillow is taller because of the density so maybe not great for stomach sleepers but works well for back and side sleeping. I bought this because I tried the same pillow at my sister’s house and woke up without neck pain for the first time in forever. Honestly better than my $100 pillow.
