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.

Excellent customer service and quality
Size: Super King, Size: Super King
Update: since my original review the company has reached out to me and apologized for the quality of the comforter i received. They replaced the comforter with a brand new one and didn't make me send back the old one either! This new one is great quality so i am very pleased. The comforter is super comfy and not too hot or too cold. It has some weight to it which i love because it makes it so much more cozy without making me too hot. I got the super king size and I love how big it is. My husband and i don't fight over the covers anymore. With this new comforter and the way they handled things i give this company and product 5 stars and would highly recommend this to anyone! Well, I just opened this comforter and already im finding issues. There are strings coming out and at least 2 stains I've found so far. Not sure if I should return this or what as I'm sure it would be really hard to fit this back into the case. Wish this was a better experience. This was very expensive too, so very disappointing.

Love this comforter.
Size: Queen
Super comfortable and light and well worth the price. Excellent quality that I didn't think I'd find again. And without the dreaded returns of trying something and it not right. It feels like the same one I bought in 2007 at BB&B on Christmas Day for half off and that was $250. So normally a $500 comforter and as a matter of fact I still have it although the feathers are kind of falling out. I'll probably just need to take it to a seamstress and have her resell a few things but I'm still keeping that as I am going to keep this. Incredible feel and very warm for an L2. The design is great. I haven't washed it yet but on order to fluff it I basically put it in the dryer for an hour on delicates with no heat. It did come sealed in a small box but it was absolutely perfect after an hour on fluff with no heat. I will end up buying another one when I get a king size bed. All I need now is a duvet that feels just like this comforter. There was no scent as some people mentioned. It smelled fresh right out of the box.

Update: replacement comforter is much better… really impressed with this small business
Size: Palatial King
Update: The comforter on my bed is now everything I hoped for: fluffy, warm, and wonderfully cozy. Getting here was a two-part story, and it’s the happy ending and the fantastic service that created it that I really want to share. I’ll be honest, my first comforter was a letdown. It arrived flat and thin and just never really… fluffed into the cozy cloud I was hoping for. I was pretty frustrated, which is why I left my original review. But then, something really nice happened. The company actually reached out to me directly. They were so kind, listened without getting defensive, and genuinely wanted to make it right. They sent a replacement, no questions asked, and the difference has been night and day. This new one is exactly what I’d imagined. It has a real, fluffy loft, it’s softer, and after letting it settle, it’s become the full, warm, and comfortable comforter I wanted from the start. My quick takeaways: · A small business that stands behind their work. This meant a lot. · Customer service was top-notch kind, FAST, and professional. · The replacement is clearly better quality: fuller, softer, and warmer. · It’s a completely different (and better) experience than the first. I really value when a company just focuses on fixing things. The way they handled this completely changed my perspective. While the first one missed the mark, their response and the quality of the replacement have made me a happy customer. I’m glad I gave them the chance to make it right, and I’m finally cozy under the comforter I was hoping for.
