Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 21-408. 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. Designed to fit the 2016-2017 Cadillac ATS, 2016-2017 Chevrolet Camaro, and more, this direct-fit catalytic converter also interchanges with OE part 12656953. Hardware is included to eliminate the hassle of working with corroded factory parts.

Didn’t hold its shape after 1 month.
Item Package Quantity: 4, Size: Queen
been using this pillow for about a month now, and here’s my honest take. At first, it was super comfortable — soft, supportive, and perfect for getting a good night’s sleep. It gave great neck support and felt like a solid upgrade. But after a few weeks, I did notice it started to lose its shape a bit. It’s still comfortable, just not as supportive as when I first got it. I find myself fluffing it more often now.

Pillow for everyone
Item Package Quantity: 2, Size: Queen
I think this pillow is too firm. I prefer a softer pillow but wanted to try this one. I may just have to get use to it. I will keep using it and see if I cannot get use to it.

Gonna get more for the guest room while I'm thinking about it.
Item Package Quantity: 4, Size: Queen
I will buy these again in a few years. I got 2 for me, and two for my man. They look super nice and full, and squish perfectly when you lay your head down on them. They are economical and priced nicely. They fluff decent when you fluff them, and I love my pillows again. These got rid of my headaches from neck trouble. I love these pillows. I'm gonna actually buy some right now for my guest room while I'm thinking about it. I compare these to that hotel I slept at once that had the most amazing pillows. Clean crisp fresh and soft. But not too soft. They are definitely soft, but cradle your head like a hug.

Well made and soft Resilient but not memory foam Good for back or tummy sleeper
Item Package Quantity: 4, Size: Queen
These pillows are well made I put them in the dryer on medium heat for 10 min 2 at a time, and they doubled in fluffiness They're soft to the touch as well as in plushness/depth They are resilient but not memory foam I don't think they would be firm enough for a side sleeper but nice for resting on your back or tummy
