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 Revolver Manifolds feature:

Non-deforming manifold outlet seal
Self-aligning exhaust seal will never compress or blow out • 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 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

Stainless Steel
Sustains exposure to ultra-high temps for superior durability • Mandrel-bent tubing for better airflow
