Virtually indestructible 100 percent stainless TorqueTubes maximize exhaust extraction, unleashing gobs of torque. TorqueTube Manifolds are the industry's only exhaust manifolds tuned to take full advantage of motorhome power. Others exhaust manifolds have short tubes designed for the higher rpm range typically used in race-type applications, Banks chief designer Bob Robe explains. This is of little value on a motorhome. We use much longer, somewhat smaller diameter, primary tubes. This and our exclusive high-velocity collector literally suck the exhaust out of the engine - boosting torque for stump-pulling guts. TorqueTubes run your exhaust 150 to 200 degrees Fahrenheit cooler. Banks TorqueTubes maximize exhaust extraction and torque. Exclusive exhaust manifolds tuned specifically for motorhomes. 100 percent stainless construction never cracks or blows. Mandrel-formed tubes tune exhaust flow for maximum torque. Seamless pulse extractor tuned to pull exhaust and slash backpressure. Ultra-thick, 5/8 inch flanges welded on both sides and machined perfectly flat. Fits so tight, it mounts without need for sealant or gaskets. Head-pipe assembly included. Includes necessary heat shielding. Accommodates spark plug heat shields, eliminating need for expensive plug wires. 5-Year Limited Warranty Torque Tube Exhaust Header System for use with 1996-2000 GM 454 Class-A Motorhome, P30
