PPEs Manifolds and Up-Pipes are designed to maximize power and flow characteristics.

The Up-Pipe bellows are internally-sleeved, made from aircraft-grade 304 stainless steel and designed with an increased inner diameter for higher flow. The entire Manifold and Up-Pipe exhaust system is designed to lower exhaust gas temperatures (EGTs) and accelerate turbo spool-up while increasing power, fuel economy and maintaining reliability.

Kit comes complete with two PPE Manifolds, two PPE Up-Pipes, a PPE Down Pipe Support Bracket, PPE 304 Stainless Steel Manifold Gaskets and Up-Pipe Gaskets.

Ceramic-Coated Manifolds option available for the High-Flow Exhaust Manifolds and Up-Pipes Kits - GM 6.6L Duramax

Ceramic coating was pioneered by 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 known benefits of the PPE Manifolds and Up-Pipes Kit which is designed to maximize power and flow characteristics. The Up-Pipe Bellows are internally-sleeved, made from aircraft-grade 304 stainless steel, and designed with an increased inner diameter for higher flow. The entire Manifolds and Up-Pipes system is designed to lower exhaust gas temperatures (EGTs), accelerate turbo spool-up while increasing power, fuel economy and reliability.

Ceramic coating creates a thermal barrier so it doesnt absorb heat as quickly as raw metal. This reduces the thermal cycle and surface temperature. Ceramic coating promotes 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 and upgrade your Duramax with the superior combination of PPE Ceramic Coated Manifolds with 304 Stainless Steel Up-Pipes Kit.

Quality Assurance Lacking
Color: White, Size: 15.7 Inches
The first set I ordered was great; super easy to install, no issues. The second set I ordered the holes on the bottom of the shelves did not match up with the holes on the bar that secures the shelves to the wall so it was impossible to attach the shelves correctly. I'm still trying to figure out a solution. TO SUMMARIZE: First set perfect; second set unusable

Happy with my purchase
Style: Industrial / Rustic, Style: Industrial / Rustic
These shelves are fantastic! The quality is excellent, assembly was quick and easy, and they look great once installed. They have a much more expensive appearance than their price suggests. I’m very happy with my purchase and would highly recommend them.

Great sturdy shelf, install can be a bit challenging
Style: 3 Tier with Tower Bar, Style: 3 Tier with Tower Bar
The shelf is great and does exactly what I wanted it to do. I will note that the instructions indicate you’re supposed to use a 6 mm drillbit to install the anchors which comes out to about a 15/64 size. I would recommend a quarter inch drillbit because I was really struggling to get those anchors in there. Several folks also said that it’s easiest to install with two people, but you don’t need two people if you have some way to prop the piece up while you’re marking the hole placements to drill (and I would definitely recommend having a level on it the entire time you’re working to make sure that it’s correct). Lastly, it is easiest to put it together first, and then mark the drill holes, put the piece aside and drill and install the anchors, and then screw it in. I will also caution folks to not overtighten the pipe connections, because the pipes will end up in a wonky direction in the end. Overall I am extremely happy with this piece and certainly for the price!!

Easy to put together. Super cute in any room
Style: 3 Tier
I fell in love with these when we were at our kids home and we installed them for them. The way my daughter-in-law decorated them, I loved it. I ordered 3 of them. I ordered a two tier for my office, because the 3 tier was too big, and i have the 3 tier in my bathroom. They look so dang cute and finishes up the wall in those areas. They are sturdy and strong. Super easy to put together. No tools required, except when you need to hang them. It will require two people to hang them. You can put them together in less than 5 minutes. Not super heavy but strong. strong to hold several things on them. I had no parts missing. Everything came packaged very nicely. Very functional. I would definitely recommend.
