Big Hoss® Bundle

Banks iQ upgradeLet 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.


Pick your look! Dual exit Big Hoss Bundle 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.)

*Note: Six-Gun & Speed-Loader/Banks iQ are recommended for off-road/racing use only. Banks' results as tested on highest level of Six-Gun with Banks iQ and recommended airflow improvements.


Duramax expertsWho knows more about your Duramax than Banks? Banks designed and built the 6.6L Sidewinder S-10, which is the quickest and fastest ever diesel-powered drag racing pickup truck.  It holds the national quarter-mile record at 7.77 seconds at 180 mph! And it did it without the billowing black smoke common with improperly tuned diesels. Moral to the story? No one knows more about boosting Duramax performance safely and reliably than Banks.

Story and photos by Chris Tobin

Most of us know that internal combustion engines are fancy air pumps and that the trick to getting more power from them is to get more air in and out of them. Just as with old-school hotrodders, installing a free-flow exhaust system and intake will go a long way toward helping airflow in and out of the engine.

However, we wanted to do more than just a typical intake and exhaust article, so we decided to improve the entire airflow path all at once on our 350,000-plus-mile 2001 Chevy LB7 Duramax truck.

We opted to install the Banks Power Big Hoss Bundle that includes a Ram-Air intake system, Techni-Cooler intercooler and boost tubes, Monster exhaust system, BigHead wastegate actuator and Six-Gun tuner with Banks iQ display/controller to replace the well worn, but still functional stock components. Additionally, we contacted our friends at Fleece Performance Engineering to get one of their drop-in LB7 Cheetah turbochargers with a custom 63mm billet compressor wheel and high-flow inconel turbine wheel. Then, to finish things off, we ordered an LB7 downpipe from Pro Fab Performance to replace the restrictive factory downpipe and hand the exhaust gasses off to the new, 4-inch diameter exhaust system.
