Let it flow.
Banks Big Hoss Bundle replaces the power-robbing factory airflow inefficiencies (including the intercooler) with free-flowing components that dramatically increase intake airflow and air density and expel exhaust with virtually no backpressure.


Colossal power with staying power.
Banks balances the improved airflow with advanced CleanTune™ Technology that nearly doubles the HP and adds up to 84% more torque than stock without adding black smoke. This is tire-shredding, scenery-blurring constant-duty power that keeps its cool while blasting you from 0-60 mph 33% quicker and nearly 200 feet before stock!

Engineered. Not thrown together.
Forget mis-matched components. Run away from tuners that can destroy your engine. Everything in the Big Hoss Bundle is engineered to work together to maximize your engine’s power, efficiency and durability. Big Hoss honors your vehicle by safely living within the limits of your engine and drivetrain. Your Duramax will run stronger and live longer!

All gains measured at the rear wheels. +155 hp/+385 lb-ft
