There are several Banks performance products, which provide different amounts of performance improvement and once in awhile even a small boost in fuel economy, Most of the Banks add-ons improve the engine exhaust system to let the engine get rid of its waste gases more efficiently, but they also have gadgets to help air intake and electronically tune how the engine delivers it power via the transmission (called Otto Mind). Your truck might have some or all of those add-ons.
Basically the objective of the various Banks pieces is to increase horsepower and torque at certain RPM ranges, mostly those that get used when the engine is operating under heavy loads (towing, hill climbing, rapid acceleration).
