Banks versus stock
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.

RV Today features Banks

It's an old episode but what Gale explains about the principles of improving the performance in your RV still applies today.


“If you're ever crossing a mountain pass and you can't seem to keep up with the pickup or RV in front of you, chances are good you're following a Banks-equipped truck.”
