Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 51578. 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 2009-2013 Chevrolet Silverado 1500, 2009-2013 GMC Sierra 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.

Good pillow protector
Size: Queen Size (Pack of 2)
Looks and feels very durable. Didn't notice and odor when opened or in use. Fits my Coop Home Goods pillow perfectly! Sleep quality is still good with these covers on.

Very nice but expensive
Size: Queen Size (Pack of 2)
I love these cases, they didn't let out as much air as I had hoped for out the sides so I only zip it up half way so my pillow stays squishy and moldable and not partially filled with air which changes the feel of your pillow. Other then that they are great, they are very soft and quite, there is no noise whatsoever and there is some thickness to it adding a little more softness to your pillow. I ended up buying a second set. I just wish it had a little more airflow through the sides so I didn't have to leave it unzipped, that kind of defeats the purpose. I also think they are a little more expensive then they should be.

Does not change the pillows effectiveness at all.
Size: King Size (Pack of 2)
As of right now, I have not noticed anything with these covers that would significantly alter the way the pillows feel. I'm greatful that they are not noisy as most other covers are. I also appreciate that they have very much the same feel as the covers that come on the pillows. One thing I can say so far with confidence is that even though this is an additional layer to my pillows, the original feeling, specially with the Eden cool+, has been the same in terms of coolness and breathability.

SUPER SOFT - GREAT QUALITY!
Size: Crescent Queen
This crescent pillow protector is more than I expected, as far as softness and just the overall quality of it. I wish my PILLOW was as nice as this protector! Definitely recommend.
