Please note: Fits all Fleetwood and National RVs except 2004 and up Powerplatform and Duraframe models. Test Vehicle: 2006 Thor 4-Winds Motorhome equipped with a 6.8L 30-valve Triton V-10 engine. While the engine is rated by the factory at 362 hp, on the dyno the stock best gain was only 242 hp. Horsepower and torque measured at rear wheels. Banks' streamlined, stainless steel TorqueTubes (shown below compared to the stock headers) are the industry's only parallel 5-tube exhaust manifolds for RVs. Unlike competitors who add a separate tube length to a 4-tube formation, Banks intEGRates five tuned-length tubes into a design that allows rotational firing of the cylinders through the exhaust, minimizing backpressure and maximizing torque. The thick, 5/8 inch flanges never warp or leak.
