Stinger® System

Banks iQ upgradeNo airflow gridlock.
Stinger replaces the power-robbing factory airflow inefficiencies with free-flowing components that dramatically increase intake airflow and air density and expel exhaust with virtually no backpressure.

A lot of power on a little fuel.
Banks balances the improved airflow with advanced CleanTune® Technology for up to 30% more HP and 40% more torque than stock without adding black smoke. This is load-hauling, hill-taming power that keeps its cool. Stinger will rocket you from 0-60 mph 36% quicker and from 40-60 mph 43% quicker when towing. And thanks to EconoMind's fuel economy features, you'll get more MPG, too. Very cool!

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

Best gains measured at rear wheels.


Pick your look! Dual exit Stinger systems include Banks' exclusive 6" X 5" ob-round (patented design) angle-cut rolled-edge tailpipe tips while single exit systems sport a 5" round tip—and then you get a choice of polished chrome-over stainless or high-temp black finish. (For black tip system add "—B" to part number.)
