Their <a href="/71-banks-power-turbocharger-down-pipe-14151">turbocharger down pipes</a> eliminate restrictive factory bottlenecks in turbocharged diesel and gas engines, allowing exhaust gases to exit more efficiently and reducing backpressure that robs power.

Drivers seeking improved throttle response will appreciate their <a href="/71-banks-power-throttle-assist-53042">throttle assist</a> technology, which sharpens accelerator input and eliminates the frustrating lag common in modern drive-by-wire systems.</p> <p>The company also offers specialized solutions like <a href="/71-banks-power-exhaust-header-5848">exhaust headers</a> that optimize scavenging and reduce exhaust gas temperatures, and <a href="/71-banks-power-engine-air-intake-heater-delete-48265">engine air intake heater deletes</a> designed to improve cold air density for better combustion in diesel applications. Each product is developed specifically for popular truck and SUV platforms including Ford, Chevy, GMC, RAM, Dodge, and Jeep vehicles.</p> <h3>Built for Enthusiasts Who Demand More</h3> <p>Banks Power products are engineered for drivers who refuse to accept factory limitations but won't sacrifice durability or emissions compliance.

Product Details

The Banks Power Monster Exhaust System delivers maximum exhaust flow and performance for 2020-2021 GM 6.6L Duramax L5P 2500/3500 HD pickup trucks. This DPF-back exhaust system features constant-diameter 5-inch mandrel-bent aluminized steel tubing that virtually eliminates backpressure after the Diesel Particulate Filter, unleashing more power and improved fuel economy while preventing dangerous trailer heat damage.

Performance Benefits:

  • 192% greater flow area compared to the stock 2.85-inch exhaust outlet
  • 85% reduction in backpressure versus factory exhaust
  • Increased horsepower and fuel efficiency
  • 15% reduction in exhaust temperature two feet behind the tip during DPF regeneration

Patented Trailer Protection Design:

  • Massive 6.5 x 7.5-inch ob-round slash-cut tip aims exhaust out to the side of the truck
  • Eliminates the risk of melting trailers during DPF regeneration cycles
  • Allows ambient air to diffuse super-heated exhaust gases that can reach extreme temperatures for up to 20 minutes
  • Prevents the jet-like blast of heat directed at towed equipment with stock exhaust

Premium Tip Options:

  • Choice of chrome-plated polished stainless steel or high-temp Cerakote matte black finish
  • Cerakote black tip maintains its color and will not turn brown from exhaust heat
  • Patented tip design provides both style and function

The Monster Exhaust System combines mandrel-bent construction for smooth, unrestricted flow with durable aluminized steel construction. This is a complete DPF-back system designed specifically for the L5P Duramax platform, offering a straightforward installation that transforms both performance and appearance.
