If you're looking for high-flowing replacement manifolds for your L5P Duramax 2017-2021 Truck, look no further than PPE 116112500 High-Flow Exhaust Manifolds With Up-Pipes. These manifolds are manufactured from a high-sil moly casting for strength and durability, and feature aircraft-grade 304 stainless steel up-pipes with bellows that are internally sleeved and made with an increased inner diameter for better flow. They're engineered to optimize horsepower and flow characteristics, lower exhaust gas temperatures (EGTs), and enhancing turbo spool-up, fuel economy, and reliability. Plus, the up-pipes are made of 11-gauge .120” Wall Stainless-Steel With 2’ Outside Diameter.

• Made with high-sil moly Iron for strength and durability

• Aircraft-grade 304 stainless steel up-pipes for better flow

• Engineered to optimize horsepower, flow characteristics, and fuel economy

• Lowers exhaust gas temperatures (EGTs)

• CARB E.O. # D-701-34

Benefits:

Enhanced Performance: Maximizes power and flow characteristics, leading to increased horsepower and torque.
Lower Exhaust Gas Temperatures (EGTs): Reduces heat stress on engine components and improves overall engine health.
Faster Turbo Spool-Up: Quicker response time and improved throttle response.
Improved Fuel Economy: Optimized exhaust flow can lead to better fuel efficiency.
Long-lasting Durability: High-quality materials and construction ensure long-term reliability.

Optional Ceramic Coating:

Advanced Thermal Protection: Ceramic coating acts as a thermal barrier, reducing heat absorption and minimizing thermal stress.
Enhanced Flow: Smoother exhaust flow leads to lower EGTs and improved performance.
Corrosion Resistance: Protects the manifold from harsh environmental conditions, extending its lifespan.
Aesthetics: Provides a sleek and durable finish.
