PPE High-Flow Exhaust Manifold & Up-Pipe Kit 116111000 | 2001-2004 Duramax 6.6L LB7

PPE High-Flow Exhaust Manifold & Up-Pipe Kit – 2001-2004 GM 6.6L Duramax (FED / 2001 CA)

The PPE High-Flow Exhaust Manifold and Up-Pipe Kit is built to maximize performance, flow characteristics, and reliability on your 2001–2004 GM 6.6L Duramax. Designed from high-sil moly cast iron and aircraft-grade 304 stainless steel, this system lowers exhaust gas temperatures (EGTs), accelerates turbo spool-up, and improves power and fuel economy while maintaining OEM reliability.

High-Flow Exhaust Manifold

• Constructed from durable high-sil moly cast iron
• Available with optional ceramic coating for enhanced thermal protection
• Improves flow, lowers EGTs, and accelerates turbo spool-up
• Long-lasting corrosion resistance and cleaner appearance

Ceramic Coating Option

• Creates a thermal barrier to reduce heat absorption
• Promotes even greater flow for reduced EGTs
• Protects against moisture, salts, fuel, and other corrosive chemicals
• Pioneered in military and Formula 1 applications

304 Stainless Steel Up-Pipe Kit

• Aircraft-grade 304 stainless steel construction
• Internally sleeved bellows for durability and high flow
• Increased inner diameter for maximum exhaust efficiency

Important Note:
The PPE LB7 3-Inch 304 Stainless Steel Down Pipe is required for installation. The stock down pipe is not compatible with this kit.

Key Benefits:

• Maximizes power and exhaust flow
• Lowers exhaust gas temperatures (EGTs)
• Improves turbo spool-up and response
• Enhances reliability and long-term durability
• Ceramic coating option available for ultimate heat management
