A Complete L5P full delete package is an all-in-one off-road upgrade designed for 2017–2025+ 6.6L Duramax L5P trucks. It combines multiple emissions-system components into a single bundled solution, helping simplify installation, improve exhaust flow, and reduce factory restrictions for performance-focused use.

These packages are commonly used in off-road or competition setups where emissions equipment like EGR, DPF, and DEF systems are removed or bypassed for better engine efficiency.

What Is Included in a Complete L5P Full Delete Package?

A full package is designed to replace the entire emissions system with matched components that work together.

Most Complete L5P full delete package setups include:

• EGR delete kit (valve and cooler block-off components)
• DPF delete exhaust pipe or full turbo-back exhaust system
• DEF system removal or bypass components
• CCV reroute kit
• High-temp gaskets, clamps, and installation hardware
• Tuning or ECU support tools (depending on package)

Some advanced bundles also include CAN bus or ECM-related support tools for newer model years.

Why Choose a Full Delete Package?

Instead of buying parts separately, a complete package ensures all components are designed to work together.

Key advantages include:

• Better compatibility between parts
• Faster installation process
• Reduced chance of fitment issues
• Balanced airflow and exhaust performance
• More complete system removal
• Cleaner, simplified engine setup

According to industry listings, full L5P bundles are designed specifically to address the limitations of factory DPF, DEF, and EGR systems in one coordinated system
