5-inch aluminized steel constant-diameter DPF-back system. Patented negative backpressure SideKick tip helps lower exhaust exit temps by 15%. Improves flow and cuts backpressure by 89% from the DPF and 9% at the turbine inlet, allowing the engine to produce more horsepower. Includes your choice of Huge Polished-Chrome or Black Cerakote Patented SideKick tip.
Banks patented negative back-pressure tip virtually eliminates back-pressure after the DPF. With 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.
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. 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.
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.
