Pacific Performance Engineering 117020100 4 Inch Stainless Steel Performance Exhaust System

The Pacific Performance Engineering 117020100 is a complete 4-inch performance exhaust system engineered specifically for 2014-2020+ GM 2500HD and 3500HD trucks equipped with the 6.6L Duramax diesel engine. This direct-fit exhaust upgrade replaces the restrictive factory system to improve exhaust flow, reduce backpressure, and unlock additional horsepower and torque from your Duramax.

Key Features:

• 4-inch mandrel-bent tubing for maximum exhaust flow and minimal restriction
• Premium 304 stainless steel construction resists corrosion and ensures long-lasting durability
• Direct bolt-on installation with no cutting or welding required
• Reduces exhaust gas temperatures (EGTs) for improved engine efficiency
• Delivers a deep, aggressive exhaust tone without excessive drone
• Compatible with both standard cab and crew cab configurations
• Maintains proper clearance with factory fuel tank and suspension components

This exhaust system is ideal for truck owners looking to maximize their Duramax's performance potential while maintaining reliability. The larger diameter piping allows the turbocharger to spool more efficiently, resulting in better throttle response and improved towing performance. Pacific Performance Engineering's precision manufacturing ensures proper fitment and professional-grade quality that stands up to the demands of heavy-duty diesel applications.
