The American Thunder systems generally deliver an aggressive interior and exterior tone and are suited to the enthusiast who wants their performance to be heard. The sound level will depend greatly on the engine and level of modifications. Like all Flowmaster systems, the benefits include improved throttle response, power and mileage. Designed for an easy fit, these systems include all necessary parts and hardware for easy installation. Covered by our Lifetime Limited Warranty.

Very nice pillowcases
Color: 06 - Beige, Size: Standard (20" X 26")
These pillowcases are really nice. They're soft and wash well. I really like the pocket on the end. It makes your pillows look nice and neat. The price is good too.

Love the sheets but GOSH THEY STINK
Color: 19 - Forest Green, Size: Queen (20" X 30")
I have the dark green sheets and bought these for extra cases to match. I would give them 5 stars if it weren’t for the fact that they smell absolutely horrible. I am so surprised after reading reviews that more people don’t mention it?! Maybe it’s more prominent in darker colors but I have washed these now 3 different times even with scent beads and still hate the smell. I wish I could accurately describe what it smells like— it’s just not good and for some reason, body heat only exacerbates it and makes the smell even worse and I wake up feeling like a smell like the sheets… which isn’t a good thing.
Besides that, I do really enjoy them. They feel great on your skin and I love the color. I wish the smell didn’t kill them so badly for me ☹️

Comfy soft pillow covers
Color: 02 - White, Size: Queen (20" X 30"), Color: 02 - White, Size: Queen (20" X 30")
Absolutely love these pillow cases! I bought 2 sets. After I received them & washed & dried them they did remain wrinkly. I just went ahead and put them on my pillows & the wrinkles went away. I continue to love the feel, coolness & comfort. Will definitely buy more.

Great soft pillow cases
Color: 03 - Navy, Size: Standard (20" X 26")
Pillow cases are beautiful and soft, great quality. I had to return them because standard were too small. I am going to order queen instead.

These Bamboo Pillowcases Made Me Realize I Sleep Hot
Color: 07 - Cream, Size: Queen (20" X 30"), Color: 07 - Cream, Size: Queen (20" X 30")
I bought these mostly because I kept hearing people talk about bamboo pillowcases and honestly thought it sounded a little overhyped, but I totally get it now. The first thing I noticed was how cool they felt compared to regular cotton. I tend to get warm when I sleep and flip my pillow a million times during the night looking for the cold side, and these actually stay noticeably cooler longer.
They also feel really soft without having that weird slippery texture some silky pillowcases have. My skin has been less irritated lately and my hair definitely looks less frizzy in the mornings. I have thick hair that tangles easily overnight, and these have helped more than I expected.
Another thing I appreciate is that they’ve washed well so far. I was worried they’d pill or lose softness after a wash cycle, but they still feel smooth and nice. They also just make the bed feel cleaner and more comfortable overall. One of those small upgrades that ends up making a bigger difference than you’d think.
