PPW, OVER 15 YEARS ON . WE ARE A.S.E CERTIFIED TECHNICIANS.FREE SUPPORT 9AM-5PM PACIFIC Exhaust Manifold 4.0L

With more power, quicker acceleration and tougher construction than ever, the new Banks Revolver™ for the Jeep 4.0 liter ('91 to '99) out muscles any competitive exhaust manifold: period! You'd think that being made from super-durable, mandrel-bent 409 stainless steel tubing and sporting a ½"-thick precision ported and machined flange was enough... but there's more. The header is fortified with a "revolver" collector which features Banks' patented "Power Pickle®" 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.Banks TorqueTube Manifolds feature:
Non-deforming manifold outlet seal
Self-aligning exhaust seal will never compress or blow out • Bolts easily to stock exhaust
Banks' patented collector design with extended center tube is designed to pull the exhaust pulses from the engine for crisp throttle response on the draw
Manifold tubes fully welded
Each tube is welded to the flange twice, inside and out
Super-duty manifold flanges
1/2"-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
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. About a year ago, Banks Power applied its 5 cylinder collector patent to the Jeep 6-cylinder header using a firing center tube andWe 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.
