Pacific Performance Engineering 117000800 3-Inch High-Flow Downpipe 2017-2020 GM 6.6L Duramax L5P

The Pacific Performance Engineering 117000800 is a high-performance 3-inch downpipe engineered specifically for 2017-2020+ GM 6.6L Duramax L5P diesel engines. Constructed from premium 304 stainless steel, this downpipe replaces the restrictive factory exhaust component to significantly improve exhaust flow and reduce backpressure.

Key Features:

• 3-inch mandrel-bent 304 stainless steel construction for maximum durability and corrosion resistance
• High-flow design reduces exhaust backpressure and improves turbocharger efficiency
• Direct bolt-on replacement for factory downpipe on 2017-2020+ GM Duramax L5P engines
• Precision-engineered fitment ensures proper installation with factory mounting points
• Increased exhaust flow supports improved throttle response and potential power gains
• TIG-welded construction provides leak-free performance

This downpipe is designed for enthusiasts looking to maximize the performance potential of their L5P Duramax while maintaining excellent build quality. The larger 3-inch diameter and smooth mandrel bends allow exhaust gases to exit more efficiently than the factory component, reducing turbo lag and allowing the engine to breathe more freely. Professional installation is recommended for proper fitment and optimal performance.
