Virtually indestructible 100% stainless TorqueTubes maximize exhaust extraction, unleashing gobs of torque. Exclusive tuned-length, parallel 5-tube exhaust manifolds designed specifically for motorhomes. 5-Year Limited stainless steel construction never cracks or blows. Mandrel-formed tubes tune exhaust flow for maximum torque. Patented PowerPickle pulse converter maximizes exhaust extraction (see the big PowerPickle). 1/2 inch thick flanges never warp. Flanges welded on both sides, then milled flat. Hardware included. 5-Year Limited Warranty. Banks' streamlined, stainless steel TorqueTubes 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, 1/2 inch flanges never warp or leak. Maximize exhaust extraction and torque. And check out that amazing Power Pickle!
