Youd think that being made from super-durable, mandrel-bent 409 stainless steel tubing and sporting a 1/2 in. thick precision ported and machined flange was enough... but theres more. The header is fortified with a in.Revolver in. collector which features Banks patented in.Power Pickle in. 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.
