Why it is Better

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' Cerakote black tip will not turn brown with heat.

Up The Flow

Banks patented negative back-pressure tip virtually eliminates back-pressure after the DPF.

With a rocket nozzle-like tip, exhaust gasses are literally sucked out of the end of the exhaust, reducing back pressure all the back up to the turbo inlet.

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 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.
