Unmatched Flow for L5P Duramax

Unlock the true potential of your 2017-2019 GM 6.6L Duramax L5P 2500/3500 HD with the Banks Power 5-inch Monster Exhaust. This DPF-back system is engineered to eliminate the restrictive factory exhaust, providing a massive 192% increase in flow area for superior engine performance.

Performance and Protection

• Massive Flow: 5-inch constant-diameter mandrel-bent aluminized steel tubing.
• Backpressure Reduction: Cuts backpressure by 85% compared to stock, allowing for better throttle response.
• Lower Temps: Reduces exhaust exit temperatures by 15%, helping to prevent trailer meltdown during heavy towing.
• Patented SideKick Tip: Includes a polished chrome tip designed to pull cool air into the exhaust stream.

The stock exhaust nozzle is a major bottleneck for the L5P engine. By upgrading to the Banks Monster Exhaust, you allow your engine to breathe freely, resulting in more consistent power delivery and improved efficiency. The patented SideKick tip is not just for looks; it uses a venturi effect to draw in ambient air, which significantly lowers exhaust gas temperatures as they exit the system. This is a vital upgrade for anyone who uses their truck for towing or heavy-duty work. The aluminized steel construction offers a perfect balance of durability and value, ensuring your exhaust system withstands the rigors of daily use.
