Description

50 States Emissions Legal (E.O. D-701-34) PPE High-Flow Manifolds are made from cast, high-sil moly. The PPE Up-Pipe bellows are internally sleeved, made from aircraft-grade 304 stainless steel, and designed with increased inner diameter for higher flow. The entire Manifold and Up-Pipe exhaust system are designed to maximize power and flow characteristics, lower exhaust gas temperatures (EGTs) and accelerate turbo spool-up while increasing power, fuel economy, and maintaining reliability.

Ceramic coating is available as an option for High-Flow Exhaust Manifolds.

Ceramic coating was pioneered by the military and defense industries. Now considered a standard in high-performance applications like Formula 1 and military jet aircraft. This same process is available to you - today.

The Ceramic-Coating option enhances the existing benefits of the PPE Manifolds and Up-Pipes Kit which is specifically designed to maximize power and flow characteristics. Ceramic coating creates a thermal barrier and doesn't absorb heat as quickly as raw metal. This reduces the thermal cycle and surface temperature.

The ceramic coating promotes even greater flow, which means lower exhaust gas temperatures (EGTs). Ceramic coating also offers long-lasting protection against moisture, road salts, oil, fuel, and other corrosive chemicals. Plus, ceramic coating keeps your PPE Manifolds looking great - for a long, long time.

Choose the Ceramic Coating Option added to your PPE Manifolds and upgrade your GM 6.6L Duramax with the superior combination of PPE Manifolds with 304 Stainless Steel Up-Pipes Kit.

Complete your upgrade with a PPE Stainless 3 Inch, 304 Steel Down Pipe.

Important: The factory downpipe (2001-2004 LB7 only) does not fit aftermarket manifolds and up-pipes.

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.

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.
