Fabspeed OEM Center Muffler Reinforcement - 997/991 Porsche GT3 | GT3RSThe GT3 Muffler Reinforcement Brace is designed to extend the fatigue life of the factory muffler.

The varying internal pressures generated by the exhaust gases cause a repeated expansion and contraction leading to a classic fatigue failure. The Fabspeed brace is designed to reduce the magnitude of this deflection resulting in a longer service life. This small modification can save you
The GT3 Muffler Reinforcement Brace is designed to extend the fatigue life of the factory muffler. The OEM muffler’s metal skin fractures due to an "oil can" effect. The varying internal pressures generated by the exhaust gases cause a repeated expansion and contraction leading to a classic fatigue failure.

Nice but dissapointing
So it sometimes stays cool but if it’s under a blanket and you have your body on it at all it will get warm but the spots you don’t use will get cool sometimes. I am very disappointed in the material though because it’s like my dry skin scratched the pillow case all over which makes me question it and I don’t think I would buy again.

Soft and smooth cover
Color: Grey, Size: Body（20"X 54"）
This is a nice pillow cover overall. The fabric feels good and it's comfortable to sleep on, especially compared to a more basic cotton cover. It is maybe a little thinner than I expected, so if you want something thick and heavy this probably isn't that. But for a soft smooth cover that fits and feels decent, I think it's worth it. No major complaints from me after using it.

These are the ones you want
Color: Grey, Size: Body（20"X 54"）
May need to iron them out when wash/dried but my old ones still look new- soft, cooling, smooth, color is still great. Not itchy or cheap feeling. Buying a new set for family.

Very nice pillowcases
Color: Haze Blue, Size: 2 Pack Standard（20"X 26"）
Very pretty pillowcases. I washed them in cold water and dried them on low before using. They came out a little wrinkly but smoothed out on the pillow. The fabric is shiny and rich looking. It's not hot yet, here in Texas, but I am anticipating the coolness of these pillowcases to feel very nice. I appreciate the envelope closure. It gives it a finished look. There was no odd odor. They feel good like they'll last for a long time. I am a satisfied customer.

Body pillow covers
Color: White, Size: Body（20"X 54"）
I ordered the body pillow covers. They fit my pillow perfectly and the fabric is smooth and silky, but I did not find them cooling.
