Eliminates factory restrictions with free-flowing intake and exhaust components. Banks PowerPack includes stainless-steel TorqueTubes, the industry’s only exhaust manifolds specifically tuned for use in motorhomes. Banks scouts out factory-bred sloppiness and restrictions, replacing them with free-flowing, durable intake and exhaust components that work in concert to optimize power, torque, mileage and durability. PowerPack attains top gains of +79 hp and +96 lb-ft torque, with 19 percent better fuel economy – without expensive high octane. Test vehicle: 31-foot GM 7.4L motorhome, P-30 chassis, throttle-body injected. Horsepower and torque measured at rear wheels. Important: Some vehicle configurations require an extension kit for proper fit. Wheelbases over 178 inch require exhaust extension kit. Wheelbases shorter than 158 inch require some custom installation. Measure wheelbase length from center front wheel to center drive wheel.
