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.

• 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
