PPE 116112520 MANIFOLDS AND UP-PIPES-BLACK FOR 17+ GM DURAMAX 6.6L L5P

Features:

• Significant reduction in exhaust back-pressure
• Lower EGTs, better turbo efficiency and fuel economy
• Sil-moly cast iron construction 
• Two-inch Free-Flow up-pipes with sleeved bellows
• Up-pipes compatible with factory heat shields
• Exhaust manifold gaskets with high-temp coating included
• Upper and lower up-pipe gaskets included
• Manifold bolts, studs, and spacers included

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.

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

Enhance the performance of your GM Duramax 6.6L L5P engine with the PPE 116112520 Manifolds and Up-Pipes in sleek black finish. These high-quality components are engineered to elevate your vehicle's power and efficiency while ensuring compliance with 50 States Emissions regulations (E.O. D-701-34).

Crafted from durable cast high-sil moly, the PPE High-Flow Manifolds optimize airflow and are built to last. The Up-Pipe bellows, internally sleeved with aircraft-grade 304 stainless steel, feature an increased inner diameter FOR superior flow characteristics. This comprehensive Manifold and Up-Pipe system is designed to reduce exhaust gas temperatures (EGTs), enhance turbo spool-up, and improve power output and fuel economy without compromising reliability.

FOR added performance and longevity, the Ceramic Coating option is available FOR the High-Flow Exhaust Manifolds. This advanced coating technology, trusted by military and high-performance industries, provides a thermal barrier that minimizes heat absorption, reduces thermal cycles, and lowers surface temperatures – contributing to improved flow and decreased EGTs. Additionally, the ceramic coating offers long-term protection against various corrosive elements, ensuring the longevity and aesthetics of your PPE Manifolds.

To complete your vehicle upgrade, pair the Manifolds and Up-Pipes Kit with the PPE Stainless 3 Inch, 304 Steel Down Pipe. FOR GM 6.6L Duramax vehicles from 2017 onwards, these black-coated components deliver a winning combination of performance, durability, and style.

Note: To ensure compatibility, please be aware that the factory downpipe (2001-2004 LB7 only) does not fit aftermarket manifolds and up-pipes. Elevate your driving experience with the PPE Manifolds and Up-Pipes Kit – the ultimate choice FOR maximizing your GM Duramax's potential.
