PPE 116111435 MANIFOLDS AND UP-PIPES Y PIPE- SILVER FOR 04-05 GM DURAMAX 6.6L LLY

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.

• Manifolds and Up-Pipes GM 2004.5-2005 Y Pipe LLY - Silver

Important: The factory downpipe (2001-2004 LB7 only) does not fit aftermarket manifolds and up-pipes.

Elevate the performance of your 2004.5-2005 GM Duramax 6.6L LLY with the PPE 116111435 Manifolds and Up-Pipes Y Pipe in Silver. This state-of-the-art exhaust system is 50 States Emissions Legal (E.O. D-701-34), ensuring compliance without sacrificing power. Constructed from cast, high-sil moly, the manifolds are designed FOR high flow, while the up-pipe bellows utilize aircraft-grade 304 stainless steel to enhance durability and performance.

These high-flow components feature an increased inner diameter, engineered to maximize exhaust flow characteristics, which leads to reduced exhaust gas temperatures (EGTs) and accelerated turbo spool-up. The result is a noticeable boost in power, improved fuel economy, and exceptional reliability—qualities every truck owner aims FOR.

FOR those seeking even greater enhancements, the optional ceramic coating offers remarkable benefits. Originally developed FOR military and defense applications, this advanced coating acts as a thermal barrier, effectively reducing heat absorption compared to raw metal. By lowering thermal cycles and surface temperatures, the ceramic coating promotes even higher flow rates, ensuring your exhaust system operates efficiently while protecting against corrosive elements such as moisture, road salts, oil, and fuel.

The aesthetic appeal of your PPE Manifolds is preserved thanks to the ceramic coating, which keeps them looking pristine. FOR those fully committed to performance, consider completing your upgrade with a PPE Stainless 3 Inch, 304 Steel Down Pipe FOR an optimized exhaust system.

The PPE 116111435 Manifolds and Up-Pipes Y Pipe are the ideal choice FOR any GM 2004.5-2005 LLY owner looking to achieve optimal performance and reliability. Note: The factory downpipe from 2001-2004 LB7 models is incompatible with aftermarket installations.
