Why You Need It

The Banks Monster Exhaust is ONLY true 5" DPF-back exhaust system for 2024-2026 Chevy/GMC 2500/3500 Duramax 6.6L trucks. Increasing diameter from the stock 4" to 5" from the DPF to the tailpipe results in a measurable decrease in exhaust backpressure. This reduction in backpressure liberates power during the exhaust stroke, sharpens turbo response, and increases fuel economy.

Why It's Better

  • Improves power and fuel economy
  • The only true 5" DPF-back exhaust system
  • Side exit prevents melting your trailer during regen
  • Looks better than stock
  • Stainless steel construction

Innovative Electronics

In 2024, GM added additional emission-related checks for the exhaust system, measuring the Diesel Particulate Filter's pressure differential. When exhaust back pressure is reduced after the DPF, such as with a 5" exhaust, the engine control module thinks the DPF is over-full with soot and reduces engine power to protect itself, when in reality, the DPF may be empty and free-flowing.

To overcome this obstacle, we engineered the Banks Exhaust Pressure Control Module (U.S. Patent 12618353), which installs in-line with the DPF delta pressure sensor. The module recalibrates the DPF pressure sensor signal to the ECM, providing corrected data while permitting significantly improved exhaust flow.

Drop The Pressure

Banks negative back-pressure tip virtually eliminates back-pressure after the DPF. With a side-draft rocket nozzle-like tip, exhaust gases are literally sucked out of the end of the exhaust.

With pressure sensors installed, this negative exhaust pressure resulted in an impressive 9% reduction all the way back to the turbine inlet. No other exhaust for 2024+ Duramax trucks can provide this level of pressure reduction.

Change Your Look

Duramax owners can choose from two huge 6.5 x 7.5-inch ob-round slash-cut exhaust tips: chrome-plated polished stainless steel or high-temp Cerakote matte black. And, unlike other brands, Banks' Cerakote black or Chrome tip will not turn brown with heat.

Don't Be Decieved

With the stock exhaust nozzle measuring 2.85-inch compared to the Monster Exhausts massive 5-inch outlet, the Banks system offers a 192% greater flow area than stock.
Comparison of the Banks Monster Exhaust to the stock 2.85

The Monster Exhaust boasts 85% less backpressure than stock, leading to more power and increased fuel economy.

Drop That Heat

The Monster Exhaust also provides a 15% reduction in exhaust temperature two feet behind the tip during regen! The Diesel Particulate Filter (DPF) on the Duramax L5P is cleaned through regeneration in which scorching exhaust gas temperatures can last up to 20 minutes while driving.

Unlike the stock Duramax exhaust, which directs a prolonged jet-like blast of super-heated exhaust gas directly at anything being towed, the Monster Exhaust is aimed out to the side of the truck. This allows ambient air to diffuse the heated gas, eliminating the risk of melting a trailer, which has been reported by many Duramax owners.
