High-Flow Exhaust Manifold and Up-Pipe Kit for 2001-2004 (FED / 2001 CA) GM 6.6L Duramax

PPE High-Flow Manifold is made from high-sil moly cast iron. 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.

High-Flow Exhaust Manifold

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

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 Manifold and Up-Pipe 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 Manifold looking great - for a long, long time.

304 Stainless Steel Up-Pipe Kit

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

Note: PPE LB7 Down Pipe is required for the installation of this kit. The stock down pipe is not compatible with this kit. Complete your upgrade with a PPE 3-Inch 304 Stainless Steel Down Pipe.

Fantastistic! Really really nice!

I want to start this off by saying these are truly nice! Very well made! Could kill a bear with them. Way to happy to have them on my truck. They flow nice and push my turbo with authority! I have personally seen lower egts and a bump in fuel mileage on a nearly stock truck. They are really well packaged also! You will recieve one big box with three tighter sexier little boxes inside! theyre all padded up and theyre even individually wrapped in what i assume is to keep ambient moisture away from them during shipping. Somone at PPE is looking out for the people who are buying these products and understands that if they get it to your door nicely and undamaged theyll only have happy customers! I am one auch customer!

I will not lie to everyone there is a secret about this particular variety of manifold although im afraid if i tell everyone in this review i may universally ruin its many applications for others. So ill leave it to those dedicated to research and an open mind.

So i gave this four stars only because i have not a clue as to why they used socket cap (allen keyed) bolts in this application. Second reason they get fours stars, PPE is rightfully proud to display its brand and signigture all over these bueaties (mine are silver, highly recomend it!) However, the places they put their embossing and raised lettering interferes with the tools used to install these bad girls. Prepare to cut a nice long allen key (8mm) and stuff it in a socket. The longer allen key the better. Youre gonna want some swivel head rachets or universal joint adapters for this one. Oh and getting a torque wrench in there gooooood luck. I do recomend a floppy toppy adjustable reachin husky ratchet for this whole job makes quick work of it. Just liberally soak the old hardware and fasteners in penetrant over a few days before you start this project, i believe thats what helped me alot!! PPE does it again with another well performing engineered solution for all early duramaxs

great

sounds great on my LB7. deeper sounder matched with their down pipe

Best manifolds around

Definitely getting quality for what you’re paying for in this product truck runs ten times better with them! Very excited to see what’s to come with the truck
