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.
