Banks Power Revolver 91-99 Jeep Wrangler 4.0L Headers

With more power, quicker acceleration and tougher construction than ever, the new Banks Revolver out muscles any competitive exhaust manifold: period! You'd think that being made from super-durable, mandrel-bent 400 stainless steel tubing and sporting a 1/2 inch thick precision ported and machined flange was enough - but there's more. The header is fortified with a Revolver collector which features Banks patented PowerPickle exhaust collector technology. The Revolver manifold features a longer center tube in the 6 cylinder exhaust collector which captures exhaust pulse action and turns it into massive torque throughout the operating range. Powering through the roughest terrain is no longer a question. And cracking - a thing of the past when you arm your Jeep with Banks TorqueTubes. Features: Bolts easily to stock exhaust, Revolver Collector (Banks patented collector design with extended center tube is designed to pull the exhaust pulses from the engine for crisp throttle response), Manifold tubes fully welded, Each tube is welded to the flange twice (inside and out), Super-duty manifold flanges, 1/2 inch thick flanges never warp or crack, Computer-controlled machining, Precision port-match to cylinder head, Unrestricted Exhaust Ports, Tubes sized and shaped to match cylinder-head exhaust port, Precision-milled manifold flange (Milled dead-flat after welding, for durability and a perfect seal every time), Stainless Steel (Sustains exposure to ultra-high temps for superior durability), Mandrel-bent tubing for better airflow. Banks TorqueTube headers have been the best available power producers for quite a while. Recently, Banks Power applied its 5 cylinder collector patent to the Jeep 6-cylinder header using a firing center tube and We Kicked Our Own Ass! The New Revolver header matches the low end of the previous TorqueTube design and adds a ton of top end power to boot.
