PPE 116111035 EXHAUST MANIFOLD W/UP-PIPES (2001 CA, 01-04 FED) SILVER FOR 01-04 GM DURAMAX 6.6L LB7

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.

The PPE 116111035 Exhaust Manifold with Up-Pipes is engineered to elevate the performance of your 2001-2004 GM Duramax 6.6L LB7 engine. Designed with precision, this exhaust manifold system incorporates cutting-edge technologies and materials, ensuring it meets the stringent standards of emissions regulations across all 50 states (E.O. D-701-34). Crafted from durable cast, high-sil moly, the manifold guarantees long-lasting performance while promoting significant power and fuel efficiency improvements.

The included Up-Pipes feature internally sleeved bellows made from aerospace-grade 304 stainless steel, boasting an increased inner diameter FOR optimal exhaust flow. This intelligent design not only enhances power output but also contributes to lower exhaust gas temperatures (EGTs) and quicker turbo spool-up, providing a noticeable boost in driving performance.

FOR those seeking additional benefits, the optional ceramic coating offers exceptional advantages. This advanced thermal barrier technology, rooted in military applications and now a standard in high-performance racing, minimizes heat absorption and prolongs the lifespan of the manifold. With ceramic coating, the flow characteristics are further enhanced, leading to even lower EGTs and a more reliable system.

Moreover, the ceramic coating protects against corrosion from moisture, road salts, and other harsh chemicals, ensuring your PPE Manifolds maintain their impressive appearance and functionality over time. Completing your upgrade with a PPE Stainless 3 Inch, 304 Steel Down Pipe will trans FORm your GM 6.6L Duramax into a powerhouse of performance without compromising reliability.

Elevate your driving experience with the unparalleled power, efficiency, and aesthetics of the PPE 116111035 Exhaust Manifold with Up-Pipes. Note: The factory downpipe is incompatible with aftermarket manifold systems.
