Six-Gun® Bundle

Banks iQ upgradeNo airflow gridlock.

Banks Six-Gun Bundle 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.

Power that keeps its cool.

Banks balances the improved airflow with advanced CleanTune® Technology that delivers up to 54% more horsepower and 68% more torque than stock without adding black smoke. This is tire-smoking, scenery-blurring power that keeps its cool while rocketing you from 0-60 mph 24% quicker and 154 feet ahead of stock!

Live long & run strong.

Forget mismatched components. Run away from tuners that can destroy your engine. Everything in the Six-Gun Bundle is engineered to work together to maximize your engine’s power, efficiency and durability. Six-Gun Bundle honors your vehicle by safely living within the limits of your engine and powertrain. Your Duramax will run stronger and live longer!


Pick your look! Six-Gun Bundles include Banks' single exit systems with a 5" round tip—and you get a choice of polished chrome-over stainless or high-temp black finish. (For black tip system add "—B" to part number.)

LLY Six-Gun Bundle: The Porsche 944 Turbo Had Problems Keeping Up With Me

2005-07-10

Jon of Indian Springs, Ohio, installed a Six-Gun Bundle on an ’05 GMC Sierra Duramax LLY with a 6.6L turbo-diesel

Wow, Wow, Wow. Just put the Six-Gun Bundle in last night at my brother’s shop. Made some runs down a 1/4 mile street behind the shop. Wanted to make comparison on the newfound power so I ran the truck against a Porsche 944 Turbo that my brother was working on and I think I left him looking for some more power on the 944. He had some problems keeping up with me. This is the most impressive upgrade I have ever done on any of my vehicles. Thanks Banks for an excellent system.

Gale Banks, an old (and I mean that in a positive way) hot rodder … is a bit of a perfectionist, always trying to outdo even himself.
