Change Your Look
Duramax owners can choose from two huge patented 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' polished chrome tip will not turn brown with heat.
Drop The Pressure
Banks patented negative back-pressure tip virtually eliminates back-pressure after the DPF.
Utilizing a side-draft rocket nozzle-like tip, exhaust gasses 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 turbo inlet.
This reduction in drive pressure and parasitic losses allows your turbo to spool quicker and improves engine efficiency.
Don't Be Deceived
With the stock exhaust nozzle measuring 2.85-inch compared to the Monster Exhaust's massive 5-inch outlet, the Banks system offers a 192% greater flow area than stock.
The Monster Exhaust boasts 89% less backpressure than stock at the DPF and 9% lower at the turbine inlet, 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.
