PPE 116111420 MANIFOLDS AND UP-PIPES Y PIPE-BLACK 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 - Black

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

Enhancing the performance of your 2004.5-2005 GM Duramax 6.6L LLY, the PPE 116111420 Manifolds and Up-Pipes Y Pipe in sleek black is engineered FOR superior efficiency and power. These high-flow manifolds are crafted from durable cast high-sil moly, ensuring robust performance and long-lasting reliability. The accompanying up-pipe features internally sleeved bellows made from aircraft-grade 304 stainless steel, designed with an increased inner diameter that significantly enhances the exhaust flow.

This advanced exhaust system aims to maximize your vehicle's power and flow characteristics while lowering exhaust gas temperatures (EGTs). Experience faster turbo spool-up, improved fuel economy, and a significant boost in power without compromising on reliability.

FOR those seeking an additional edge, the optional ceramic coating takes performance to the next level. Developed FOR military and elite racing applications, this coating creates a thermal barrier that significantly reduces heat absorption compared to raw metal. The result is an even greater flow and reduced thermal cycling, ensuring lower EGTs while also providing long-lasting protection against moisture, road salts, oil, fuel, and other corrosive elements that can threaten the integrity of your exhaust system.

Not only does the ceramic coating enhance functionality, but it also keeps the PPE Manifolds looking pristine over time. Upgrade your GM Duramax with the unmatched combination of PPE Manifolds and 304 Stainless Steel Up-Pipes Kit, and consider complementing your setup with a PPE Stainless 3-Inch, 304 Steel Down Pipe FOR a complete performance trans FORmation. Note: The factory downpipe (2001-2004 LB7) is not compatible with aftermarket manifolds and up-pipes. Experience power like never be FORe with the PPE 116111420.
