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.


Gale Banks has pulled more power out of diesel engines than just about anyone-from motorhomes to record-breaking Bonneville salt racers. Banks has a history of breaking things-particularly speed records. Throughout the years, he has earned trophies at the Bonneville Salt Flats for the world's fastest pickup, fastest piston-engine automobile, and fastest passenger car. And those are just a few of his record-setting achievements.
