Banks' heavy-wall 400-series stainless TorqueTubes include two full exhaust manifold assemblies, each with a seamless high-velocity collector. Unlike the restrictive stock setup, Banks TorqueTubes literally "pull" out the exhaust, unleashing greater torque and helping the intake stroke to draw in more air. Includes all required hardware.
